Paleomagnetic studies show that the South China block was moving northward continuously from 300 to 260 Ma and has experienced an overall ∼27° clockwise rotation since then (Huang et al., 2018) ,and assuming a stationary Emeishan mantle plume, so if I want to do a numerical simulation of the geodynamics of the Emeishan mantle plume based on the above conditions. How can I do it?
Basically, I want to create a simplified geological map to accompany the description of a Palaeontological locality, as seen in many publications. I wouldn't want to concern myself with GIS since I want something more simplified and I already have a proper geological map of the area. I was thinking maybe of a designing software to use with layers?
I have generated a kmz. file of a scanned geological map. But when it is opened through Google Earth, the resolution is very low and cannot zoom in with clear colours.
Is there any method to this?
I need to create a geological map of an area overlapped with topography to attain a hillshade effect for lithological layers.
an example is given in the following figure
( source: Transactions - Geothermal Resources Council 36:1345-1354)
( I want to create a Geological map with Gneiss as a base layer. but the same unit is present within the boundary of an upper layer of Charnockite. I need to draw each without overlap)
The samples were collected from aquifer with the following lithology:
- Conglomerates, calcareous limestones sand red and green clays
- Marls, clays and white limestones
- Clays and gypsum;
I am working on Ririwai ring complex using aeromagnetic and aero-radiometric data. I have generated different maps but i need to generate the temperature of formation or curie temperature of each rock unit to augment my conclusion .
Normally, the lithosphere thickness is thicker in craton than tectonic areas. But in subduction zones, the lithosphere thickness of overriding plate is inaccurate and rough. I did not find any papers or publications that give a relative accurate vales for this thickness. Who can give me a link or paper regarding that?
As I know, the surface wave (love, Rayleigh wave)can reach the deep part (over 100km) of Earth and reflect some information by seismic technology ( maybe tomography earthquake seismology). The classical model of subduction zone is that the lithosphere-asthenosphere boundary of overriding plate should be over the position of primary melt in subduction zone, should it be? Or it is possible that this boundary is below the position, where the primary melt happen. In other words, the primary magma could be in the lithosphere of the subducted plate?

Exploration of Salar brines (containing high concentrations of dissolved salts like Lithium, Potassium, Magnesium, etc) found below the surface of dried lake-beds (Playas) is generally carried out through surface geological mapping, geophysical surveys and brine sampling through drilling.
Whether characteristic biota - both living & fossils - can be an added exploration tool?
I am looking for the latest geological map of Ethiopia. And, I hope some people may have it at hand. So, please share me if you don't mind! You can message me, if you don't want to share it on public.
Thanks in advance for your cooperation!
The paleostress orientations inferred from the orientations of dikes (see attached figure) indicate that none of the principal stress axes is oriented at neither vertical nor horizontal orientation, rather all of them are oriented at the intermediate orientation between the vertical and horizontal orientations. Hence, the fact violates the Anderson theory of faulting, where one of the principal stress axes must be vertical due to the stress boundary condition at the surface of the earth.
What could be the plausible explanation?
When I build 3D geological modeling, I use 2D (3D) geology-geophysic forward modeling profiles (constrained by prior geological information such as geological mapping and drill hole), because those profiles have clear geological significance. Although I can calculate 3D inversion constrained by 3D forward modeling (by using UBC and Modelwision software) there is still difference between 3D geophysical inversion 2D profiles) and 3D forward modeling (2D profiles). How to deal with this difference between geophysical inversion and forwarding in my modeling and prospecting.
What's the advantages and disadvantages of geophysical forwarding modeling and inversion in 3D geological modeling and prospecting?
There is a project plan to provide a 130m deep well in this area but I am concerned about the transmissivity of the underlying granite. I have no info on the condition of the rock, or any aquifer it contains, potential yield etc. Any evidence as to likely success in this formation would be welcome.
Kindly, could any one let me know how to fix the value of concavity index (-0.4) when use TecDEM software. fixing this value is very important to extract the steepness index which could be depend on in the evaluation of tectonics?
This is more an update, not really a question. But did you know that Harris et al. (2014), doi:10.1016/j.margeo.2014.01.011) have done a great job with making a worldwide map of marine geomorphology? The map may be downloaded (as zipped shape files) from http://www.bluehabitats.org/
Hello Respected researchers.
I am looking forward to you about coal body modeling in Surpac software. I have less amount of boreholes at one side of body with geological map of that area. I don’t have any geophysical data of that area. Is there any possible way to build a model with comparing the borehole data with cross sections.

what should be the technique to convert point data to make a surface
I am looking for the geological map (any scale) of northern Libya to establish the continuity of the mesozoic outcrops of southern Tunisia; detail paper or description if possible.
I have data sets of the strike of multiple joints. Additionally, I have the data set for the dip of the joint plane. I would like to know about the plotting of this data on a geological map. Each location has two to three sets or joints (or even more). The density of the location is also very high (I have lots of location and its data). Can anyone share some literature where this kind of data is shown and interpreted?
In remote sensing, the RTM method seems to have some advantages in geological mapping, where can I get Rotation-Variant Template Matching algorithm for ENVI? Thank you for your help.
We have been seeing many countries still don't have good resolution geological maps of their territory. In such situation remote sensing is an alternative for independent researchers. Understanding of Photogeology is the most for this.
I’m a specialist of vertebrate tracks. During a long stay at Kinshasa, I discovered a number of tracks of early mammals, on slabs of purple sandstone. The tracks are of bad quality; however, they are interesting: they would be the first vertebrate tracks in Congo, and they are very similar to Brasilichnium elusivum and similar tracks, from Botucatu Formation and Caiuá Group, LK, in Brazil. Those sandstones are very common at Kinshasa, also on the sidewalks. They came from natural outcrops and quarries inside W outskirts of the town of Kinshasa, on the banks of Congo river, in the quarters of Kinsuka, Mbudi, Pompage. I could not find in situ or in internet any detailed Geological map of the Phanerozoic of Congo and of Kinshasa. To publish these tracks, I need the name and if possible the dating of this formation. Can any colleague help me? Thank you. Giuseppe Leonardi
I'm trying to obtain topographic maps of the island of Naxos in Greece. Our aim is to conduct an undergraduate course in geological mapping at the scale of 1:10,000. Ideally we would need maps at the scale of 1:25,000 as a base map, such as issued by the official cartographic survey.
I'd be very grateful for any weblinks or contact addresses.
Thank you all in advance,

I am presently working on the evolution of a part of the basement complex rocks in Nigeria. The area is marked by shear zones. My field visits have shown that the shear zones cut across granitic gneisses, pegmatite (extensive and comprises mainly feldspar) and some mica schist. A part of my objectives is to determine the strain (quantitatively) by way of field and laboratory analysis. I need guide and may be peer-reviewed papers that have addressed such case(s). Thank you.

I have to give AHP weights for all of the above mentioned layers, could you please suggest me, what is the criteria I have to follow in this case.
Any suggestion from experts.
Thanks for your attention.
I need a global (or for Brazil) map of soil surface porosity. Could someone tell me where I can download it? I need the map so that I can work with it with some GIS to extract specific coordinate data.
I downloaded the 'GLHYMPS' from http://crustalpermeability.weebly.com/glhymps.html, but I found it a bit strange because the porosity of the soil for a whole state is only 0.01%.
If someone could help me by indicating some place to download, I will be very grateful.
Good week to everyone!
I have a gravity anomaly map, Bouguer and terrain corrected, from which I wish to estimate the crustal thickness. Is there a standard formula with which I could do this? (Given an assumed density for the crust). Anomaly is in mgal.
Thanks in advance!

The importance of the River Nile cannot be underscored enough. The Nile, which is 6,853 km (4,258 miles) long, is an “international” river as its drainage basin covers eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, Congo-Kinshasa, Kenya, Ethiopia, Eritrea, South Sudan, Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan. It flows from Lake Victoria to the Mediterranean, and covers an area of at least 3,349,000 square Kilometers.
I want to determine the sediment rate of N and P in water volume for small reservoirs covering less than 3 ha. The referenced documents are old , and i can not download them. Who can give me some good suggestions? Thanks

For estimation of local recoverable reserves in open pit mines which one of “drill holes spacing” or “blasting patterns dimensions” for panel size and SMU size” or “ blasting pattern dimensions” or “blasting holes spacing” for SMU size could be suitable selections?
I was wondering if reconstructing paleo depths of a subduction zone (with P-T-t path) would be possible to understand what was the original dip of that subduction zone and in which direction it went roll-back.
The area in question is underlain by a thick sequence of dark/black shales. However, lead/zinc deposits in the area are most located in faults/fractures within this thick layer of shale.However, most of the fractures especially with certain trends are barren> This scenario most often makes it slightly problematic to locate the minerals using geophysical methods especially electrical resistivity methods because of the masking effect of the shaly horizon.Can the mineralization in this scenario be detected directly using the Forward Gauss VR8000 detector? Are there specific/typical range of resistivity/magnetic/gravity values that can be used for the lead/zinc in this case?
