Two petrographic settings of carbonaceous components, mainly filling open fractures and occasionally enclosed in shock‐melt veins, were found in the recently fallen Tissint Martian meteorite. The presence in shock‐melt veins and the deuterium enrichments (δD up to +1183‰) of these components clearly indicate a pristine Martian origin. The carbonaceous components are kerogen‐like, based on micro‐Raman spectra and multielemental ratios, and were probably deposited from fluids in shock‐induced fractures in the parent rock of Tissint. After precipitation of the organic matter, the rock experienced another severe shock event, producing the melt veins that encapsulated a part of the organic matter. The C isotopic compositions of the organic matter (δ13C = −12.8 to −33.1‰) are significantly lighter than Martian atmospheric CO2 and carbonate, providing a tantalizing hint for a possible biotic process. Alternatively, the organic matter could be derived from carbonaceous chondrites, as insoluble organic matter from the latter has similar chemical and isotopic compositions. The presence of organic‐rich fluids that infiltrated rocks near the surface of Mars has significant implications for the study of Martian paleoenvironment and perhaps to search for possible ancient biological activities on Mars.

“…Micro-scale variation of elements and isotopes in hydrothermal minerals, obtained by micro-beam analysis, can provide crucial clues for revealing the source and evolution of ore-forming elements and associated fluids, and the cause of hydrothermal mineral precipitation (Barker et al, 2009;Nishizawa et al, 2010;Ye et al, 2011;Jin et al, 2016;Deng et al, 2017). Laser-ablation multi-collector inductively coupled plasma mass spectroscopy (LA-MC-ICPMS) and secondary ion mass spectroscopy (SIMS) can accurately analyze isotopic compositions of hydrothermal minerals in situ (Ikehata et al, 2008;Zhang et al, 2014;Yuan et al, 2015;Bao et al, 2016). Here we use the Fule deposit as a case study, utilizing NanoSIMS in situ S, femtosecond (fs) LA-MC-ICPMS in situ Pb, and bulk C-O-S isotope analyses, together with a detailed dataset of the ore deposit geology and mineralogy, aimed at revealing the ore genesis of the Fule deposit and its relationship with the ELIP.…”

Ore genesis of the Fule Pb Zn deposit and its relationship with the Emeishan Large Igneous Province: Evidence from mineralogy, bulk C O S and in situ S Pb isotopes

Magmatic activity plays an important role in mineralization, but little is understood of its role with respect to carbonate-hosted stratabound epigenetic Pb-Zn deposits. The Fule Pb-Zn deposit (~10 Mt of sulfide ore with mean grades of 15-20 wt. % Zn + Pb), is stratigraphically placed in middle Permian strata and spatially (~1 m) associated with late Permian continental flood basalts of the Emeishan Large Igneous Province (ELIP). It thus provides an ideal case to investigate its genetic relationship with the ELIP. In addition, the Fule deposit is characterized by high concentrations of Ag, Cd, Ge and Ga, and contains a variety of Cu and Ni sulfide minerals. Syn-ore calcite (δ 13 C = +2.57-+3.01‰) and associated fluids (δ 13 C = +2.96-+3.40‰) have δ 13 C values similar to those of fresh limestone (δ 13 C = +1.58-+2.63‰), but the δ 18 O values of calcite (+16.83-+19.92‰) and associated fluids (+7.80-+10.89‰) are distinctly lower than those of limestone (δ 18 O = +21.85-+23.61‰). This means that C is mainly derived from limestone, whereas the O isotope signature may be related to water/rock (W/R) interaction between mantle and/or metamorphic fluids and limestone. δ 34 S values of sulfide minerals obtained by in situ NanoSIMS and conventional bulk techniques record a range of +9.8-+23.1‰ and +10.04-+16.43‰, respectively, reflecting the enrichment of heavy S isotopes in the oreforming fluids and thermochemical sulfate reduction (TSR) is the principal mechanism for the formation of S 2-. Cores of sulfide crystals have much higher δ 34 S values than their rims, indicating a probable mixture of multiple S reservoirs and/or a dynamic fractionation of S isotopes occurred during sulfide precipitation. The uniform femtosecond (fs) LA-MC-ICPMS in situ Pb isotopic data for galena plot in the field that differs from any of the three potential 3 sources in the region. Such signatures demonstrate that metal Pb was most likely derived from a well-mixed source of basalts, sedimentary rocks and basement rocks. We propose that (a) the enrichment in Ag, Cu, Ni, Cd, Ge and Ga, and the isotope signatures of hydrothermal minerals in the Fule region are related to fluids derived from or flowed through multiple reservoirs; (b) Emeishan magmatism provided heat, elements and associated fluids, and its basalts acted as an impermeable and protective layer; and (c) fluid mixing caused TSR, and then resulted in W/R interaction and CO2 degassing, all of which played a key role in the precipitation of hydrothermal minerals.

QSA undercounting could compromise isotope ratio analyses requiring ~1 × 10 counts per second for the major isotope and primary currents <20 pA. The error could be >8‰ for a 1 pA primary current. However, correction can be accurately applied. For instrumental mass fractionation (IMF)-corrected data, the magnitude of the error resulting from not correcting for QSA is dependent on the difference in secondary ion count rate between the unknown and standard analyses.
