What is the best conditions for formation of Ag ore deposits?

I want to know more about Mn Ag deposits.

Ag is recovered for a profit mostly from galena-bearing deposits therefore have a look at Pb-Zn deposits where high-T deposits have the highest grade:

(1)Magmatic lead-zinc deposits

(1)Polymetallic Sn-(Ag-Pb-Zn-Cu) vein-type deposits in intermediate subvolcanics (

(2)In-bearing Zn–Sn–Cu veins and replacement deposits in granites D)

(3)Polymetallic Ag-Zn-Pb skarn deposits

(1)Skarn deposits s.s.

(2)Skarn-vein-type deposits (mixed-type)

(4)Volcanic massive sulfide Pb-Zn-Cu-In deposits (VMS)

(1)Kuroko-type

(2)Besshi-type and Abitibi/ Ural-type (

(3)Cyprus-type and Atlantic-type

(4)Iberian-type/ Greenstone-belt-type

(5)VMS deposits in medium tohigh grade metamorphic terrains of unknown type

(2)Structure-relatedlead-zinc deposits

(1)Unconformity-related Pb-Zn-F-Ba deposits

(2)Thrustbound and fold-related Pb-Zn deposits

(3)Replacement deposits (sulfidic and non-sulfidic)

(3)Sedimentary lead-zinc deposits

(1)SEDEX/SMS Pb-Zn-Ag-(Ba)-FeS-(Sn) deposits

(2)Sandstone-hosted Pb-(Zn) deposits

(1)Sulfidic subtype

(2)Non-sulfidic subtype

(3)Carbonate-hosted Pb-Zn-(Ag) deposits (sulfidic and non-sulfidic)

(1)Pb-Zn-Ba-F-(Ag) flexure- to horstbound sulfidic deposits (plus gem-quality sphalerite)

(2)Pb-Zn-(As-Ba) flexure- to horstbound sulfidic-non-sulfidic

(3)Pb-Zn-Ba-Ag-(Ni-Co) horstbound sulfidic-(non-sulfidic)

(4)Pb-Zn-Ge-Mo faciesbound sulfidic

(5)Carbonate- evaporite-associated Pb-Zn deposits

(6)Karst-related non-sulfidic Ba-Zn-(Pb) deposits

(7)Non- sulfidic Zn hypogene-(supergene) replacement deposits

(4)Ge-enriched coal seams

(4)Metamorphiclead-zinc deposits

Dear colleagues,

I’m currently working on my graduation project focused on Monazite and its chemical, geological, and industrial significance. I’m looking for published research, datasets, or any recent studies related to the following topics:

Table of Contents from My Project:

Chapter 1: Introduction Geological and industrial importance of Monazite Research objectives and methodology
Chapter 2: Chemical Composition and Crystal Structure REEs, Thorium, Uranium content Crystal structure (Monoclinic) Analytical methods (XRD, SEM, EDS)
Chapter 3: Radiometric Dating U-Th-Pb dating methods (LA-ICP-MS, EPMA) Effects of metamorphism on dating accuracy
Chapter 4: Geology and Distribution Monazite in black sand and coastal sediments Major producing countries Monazite deposits in Egypt
Chapter 5: Industrial Applications REEs extraction Thorium and nuclear energy Use in electronics and environmental concerns

If you’ve published work in any of these areas, or know researchers or resources I should explore, I’d really appreciate your help.

Please feel free to share links, papers, or contact info.

Thank you!

You can copy this directly or I can shorten it or modify the tone based on your audience. Want me to make it more formal or academic?

Do you know in which rocks can be more metallic ore deposits?
