Basaltic shergottites such as Shergotty, Zagami and EET79001 contain impact melt glass pockets that are rich in Martian atmospheric gases and are known as gas-rich impact-melt (GRIM) glasses. These glasses show evidence for the presence of a Martian regolith component based on Sm and Kr isotopic studies. The GRIM glasses are sometimes embedded with...

The 80Kr excesses determined in the gas-rich impact-melt (GRIM) glasses in EET79001 and Shergotty correlate poorly with the 129XeM (Martian atmosphere) suggesting that the majority of the neutron-capture 80Krn was not shock-implanted along with 129XeM into these glasses during impact. This inference is consistent with the variations in δ80Krn exces...

Hydrogen isotopes ratios in shergottites are shown to be strongly influenced by terrestrial contamination. The difficulty in distinguishing martian variations in D/H from variable terrestial contamination is highlighted.

Elemental abundances determined in gas-rich impact-melt (GRIM) glasses from EET 79001, Shergotty Zagami, and QUE 94201 show that acid sulfate fluids interacted with the basaltic parent material at shergottite sites on Mars.

Mean vanadium valences determined by microXANES for gas-rich impact-melt (GRIM) glasses in EET79001 ranged from 3.0 to 3.6. Mean fO2 ranged from IW-1.2 to IW+1.4. Variable oxidation state is consistent with impact reduction of regolith precursors.

Hydrogen isotope ratios in the hydrous alteration mineral jarosite have been measured by ion probe, in the shergottite QUE 94201. Hydrogen isotope ratios indicate that jarosite was formed in Antarctica, or that hydrogen isotopes re-equilibrated with Antarctic water.

Sulfur isotope studies in gas-rich impact-melt glasses in shergottites indicate that sulfate is reduced to sulfide during impact melting and quenching.

Abstract— Previous studies have shown that the Kapoeta howardite, as well as several other meteorites, contains excess concentrations of cosmogenic Ne in the darkened, solar-irradiated phase compared to the light, non-irradiated phase. The two explanations offered for the nuclear production of these Ne excesses in the parent body regolith are eithe...

Abstract— Previous studies of Apollo 17 double-drive tube 79001/2 showed that portions of this lunar regolith segment have some unusual properties, such as very high Is/FeO values (Monis et al., 1989) and N contents (Stone and Clayton, 1989). To understand the geologic significance of these features in this core, we determined the grain-size distri...

We studied the inter-relationships between the major anions (SO3, Cl, and Br) and cations (FeO, CaO and MgO) using elemental abundances determined by APXS in salt assemblages of RATted (abraded) rocks at Meridiani to characterize the behavior of fluids that infiltrated into this region on Mars. A plot of SO3 versus Cl for the abraded rocks yielded...

Sulfur and iron K XANES measurements were made on GRIM glasses from EET 79001. Iron is in the ferrous state. Sulfur speciation is predominately sulfide coordination but is Fe coordinated in Lith B and, most likely, Ca coordinated in Lith A. Sulfur is abundantly present as sulfate near Martian surface based on chemical and mineralogical investigatio...

The hyperbola-straight line method (tested for Meridiani rocks) applied to Columbia Hills/West Spur rocks shows that these rocks were exposed systematically to an evaporating aqueous fluid.

Two types of solutions, (a) SO3-high and Cl-low and (b) SO3-low and Cl-high, infiltrated into rocks at Meridiani and had undergone progressive evaporation. Shergottites and nakhlites also interacted with (a)- and (b)- type solutions respectively.

The sulfate/chloride vs. Cl and chloride/bromide vs. Br relationships in the salt-assemblages on Meridiani (RAT) rock-rinds indicate that these salts likely formed by progressive evaporative concentration of brine waters filling the Endurance Crater basin

S and Cl in salts from Nakhla and from the gas-rich impact-melt ("grim") glasses in Shergotty and EET79001 suggest that these salts are produced from neutral-chloride and acid-sulfate solutions on Mars. Interaction with similar solutions generated salts occurring in Meridiani rock- rinds.

In this paper, we are proposing self-adaptive software architecture for disaster management. This system uses geo-spatial data and applies spatial collocation rule to mine spatial patterns. These spatial collocation patterns are stored as knowledge database and subsequently provided to Disaster Management teams for rescue and management. A spatial...

Chlorine and Br abundances in fracture-filling secondary salts in Nakhla veins determined in this study by Synchrotron X-ray Microprobe (Br) and Electron Microprobe (Cl) techniques compare well to the halogens determined recently by APXS instruments in soils and rock rinds at the Gusev and Meridiani sites. The salts in these Mars rocks arise from M...

Comparison of Cl and Br from Nakhla viens to MER samples suggests two kinds of brine solutions existed on Mars, one early and one late in the evaporation sequence. These solutions precipitated the secondary salts at the Meridiani and Gusev sites. We have recently reported the Cl and Br abundances determined by APS X-ray Microprobe and EMPA analyses...

Impact-melt glasses, rich in Martian atmospheric gases, contain Martian soil fines (MSF) mixed with other coarse-grained regolith fractions which are produced during impact bombardment on Mars surface.

The Cl/Br ratios in fracture-filling materials in veins in Nakhla olivine was determined using x-ray microprobe (Br) and EDX (Cl) techniques. The Cl/Br ratio of 55 (standard deviation: 13) shows that the secondary altered material is pristine, extraterrestrial and akin to the Martian soil. Additional information is contained in the original extende...

Impact-produced glasses in some martian meteorites have trapped significant amounts of the recent martian atmosphere. From literature data, we estimate that ~9% of the trapped 80Kr in these meteorites was produced from neutron capture on 79Br. Estimates of neutron fluences made from 80Kr and 149Sm for bulk samples of meteorite EET79001 indicate tha...

We calculate that ~10% of Martian atmospheric 80Kr formed by neutron capture on Mars in

We calculate that approximately 10% of martian atmospheric Kr-80 formed by neutron capture on Mars in approx. 0.5 Ga. The regolith contains even larger amounts of n-capture Kr-80 and Ar-36, which may provide clues to the evolution of the martian regolith and atmosphere. Additional information is contained in the original extended abstract.

Based on large heavy isotope enrichments in Ne and Ar in Martian atmosphere, we suggest that sulfur isotopes may show similar isotopic enrichments in atmosphere and surface samples.

Chemical compositions of impact melt glass veins, called Lithology C (Lith C) in Martian meteorite EET79001 were determined by electron microprobe analysis. A large enrichment of S, and significant enrichments of Al, Ca, and Na were observed in Lith C glass compared to Lithology A (Lith A). The S enrichment is due to mixing of plagioclase- enriched...

Abstract— Elemental and isotopic compositions of the noble gases have been determined in six North American tektites (4 bediasites and 2 georgiaites) and one Ivory Coast tektite. Radiogenically produced 4He may explain the large 4He/36Ar ratios measured relative to air, despite significant diffusive losses. The Ne isotopic composition is enriched i...

Earlier NASA spacecraft measured real-time characteristics of energetic solar protons and found the flux and some other parameters to vary widely. The only way to determine some long-term, average characteristics of solar protons is by measurement of their nuclear interaction products as a function of depth within the very few lunar rocks that have...

Previous studies have shown that many individual grains within the dark phase of the Kapoeta howardite were irradiated with energetic particles while residing on the surface of the early HED regolith. Particle tracks in these grains vary in density by more than an order of magnitude and undoubtedly were formed by energetic heavy (Fe) ions associate...

— Measured Ne isotopes in samples of shergottite ALHA77005 show variations in 21Ne/22Ne ratios and 21Ne abundances that are consistent with the presence of two cosmogenic components: a component produced by nuclear interactions of galactic cosmic rays (GCR) and a component produced at shallow shielding depths (∼0–3 cm) by energetic solar flare prot...

Greater concentrations of [21Ne]c in the dark phase of Kapoeta, compared to the light phase, may represent a large irradiation by solar protons (SCR) in the early solar system [1] or a longer galactic cosmic ray (GCR) irradiation [2]. Lunar rock studies demonstrate that the 21Ne/22Ne ratio can be used to distinguish between components produced by e...

Cosmogenic 21Ne, 22Ne, 38Ar, and 3He produced by nuclear interactions of energetic (>10 MeV) solar protons were determined in 11 depth samples of lunar rock 68815. Concentrations of these proton-produced, SCR nuclides smoothly decrease from the rock surface down to 4.3 cm, where a galactic cosmic ray (GCR) component dominates. The cosmogenic isotop...

We have determined the elemental and isotopic composition of all the noble gases in five large samples of tektites from Bedias, Texas. The purpose of this study is to determine the abundance pattern of noble gases in these samples for comparison with those determined in tektites from other strewn fields throughout the world. One prominent feature t...

Cosmogenic radionuclides produced by near-surface, nuclear interactions of energetic solar protons (approx. 10-100 MeV) were reported in several lunar rocks and a very small meteorites. We recently documented the existence and isotopic compositions of solar-produced (SCR) Ne in two lunar rocks. Here we present the first documented evidence for SCR...

Oriented lunar rock 68815, with 2 x 10^6 years of surface exposure, has become the most widely studied detector of solar cosmic ray (SCR) products. Radio-nuclides ^10Be, ^26Al, ^53Mn, ^14C, and ^81Kr measured in 68815 by several investigators have been used to estimate the long term average solar proton flux, J(sub)>10(4 pi, E > 10 MeV) and rigidit...

The authors report on isotopic measurements made on lunar rock 61016, which is one of the limited number with a known orientation history. They measure solar flare implanted [sup 4]He/[sup 3]He ratios and the depth profiles of [sup 21]Ne, [sup 22]Ne, and [sup 38]Ar isotopes produced from in situ nuclear reactions of solar flare protons with the sil...

We determined concentration profiles of Ne-21, Ne-22, and Ar-38 produced by solar protons as a function of depth in oriented lunar rock 68815. A comparison with model predictions indicate a solar proton flux J(4(pi)(r); E greater than 10 MeV) of 100-125 p/sq. cm/s and a rigidity, R0, of 85-100 MV, assuming an erosion rate of 1-2 mm/Myr. These resul...

From etched feldspar size-fractions of Kapoeta, we determine a significant excess of cosmogenic Ne-21 and Ar-38 over that produced by galactic cosmic rays. This excess component is attributed to early production by energetic solar protons and suggest that the energetic proton flux from the ancient Sun was several hundred times more intense than tha...
