Introduction: CI carbonaceous chondrites are unique rocks with solar composition (except C, N, O, and H) that were aqueously altered within several Ma after formation of the solar system. The alteration occurred in parent asteroid(s) below ~150 C [1] and led to the formation of serpentine, saponite, magnetite, pyrrhotite, pentlandite, carbonates, phosphates, and sulfates [2-4], and caused alter...

Since the Mars Science Laboratory’s (MSL), Curiosity Rover began its exploration of Yellowknife Bay in Gale Crater, it has discovered an array of basaltic and secondary mineral assemblages representative of deposition in environments ranging from aeolian sand dunes to habitable lacustrine settings. Recently, the molecular analysis of ChemCam data has shown that fluorine has been detected in mul...

Wettability and NMR surface relaxation are related to each other. Wettability controls the fluid distribution in porous media. NMR surface relaxation dictates that the fluid in contact with the mineral surface has a relaxation time shorter than its bulk value. In this study, first, the nature of wettability effect on NMR responses was demonstrated by a parameter ρ2, eff, the effective surface r...

A central loop Transient Electromagnetic TEM Resistivity Survey was conducted at the Geysir high temperature geothermal area as part the project of the author. The area is situated 110 km away from Reykjavik and lies in a shallow valley elongated north-south. Geologically it is surrounded by three volcanic domes made-up of rhyolites, hyloclastites and inter-glacial basaltic lava that obtain hea...

sarcheshmeh porphyry copper deposit is located 65 km southwest of rafsanjan in kerman province. the sarcheshmeh deposit belongs to the southeastern part of urumieh-dokhtar magmatic assemblage (i.e., dehaj-sarduyeh zone). intrusion of sarcheshmeh granodiorite stock in faulted and thrusted early-tertiary volcano-sedimentary deposits, led to mineralization in miocene. in this research, the mass ch...

the arghash area is located 45 km to southwest of neyshabour. the subvolcanic rocks in the area consist of biotite hornblende quartz monzodiorite porphyry, hornblende biotite quartz monzodiorite porphyry, hornblende monzonite porphyry, biotite hornblende monzonite porphyry, monzodiorite porphyry and biotite quartz monzodiorite porphyry units. the volcanic rocks consist of hornblende biotite dac...

the investigated area is located 30 km south of sabzevar in halakabad village. geological phenomenons in area follow a trend of nw-se. mineralization consists of metallic and non-metallic (kaolin) mineralization. disseminated and veinlet mineralization is generally associated with argillic alteration type. pyrite is the most widespread type of sulfide mineralization in halakabad occurrences. it...
