Revealing the climate of snowball Earth from Δ17O systematics of hydrothermal rocks.
The oxygen isotopic composition of hydrothermally altered rocks partly originates from the interacting fluid. We use the triple oxygen isotope composition ((17)O/(16)O, (18)O/(16)O) of Proterozoic rocks to reconstruct the (18)O/(16)O ratio of ancient meteoric waters. Some of these waters have originated from snowball Earth glaciers and thus give insight into the climate and hydrology of these c...
متن کاملCarbon and Oxygen Isotopic Systematics in Calcite and Dolomite from the Sangan Iron Skarn Deposit, Northeastern Iran
A total of 40 samples from carbonates and 8 samples from silicate rocks were analyzed from the Sangan iron skarn deposit to examine behavior of the oxygen and carbon isotopes. The higher values of ?18O are from metamorphic calcite and dolomite and lower ones are from granitic rocks. Although the ?18O and ?13C values of calcite and dolomite in marble yield the highest values in the Sangan deposi...
متن کاملThe Geology and Isotope Geochemistry of the Talc Deposits of Puebla de Lillo (Cantabrian Zone, Northern Spain)
The talc deposits of Puebla de Lillo (Cantabrian zone, Variscan belt of Iberia) are hosted by hydrothermal dolostones replacing Carboniferous limestones and are generally located adjacent to Ordovician quartzites. The talc orebodies occur as metasomatic replacement zones of the dolostones near faults or lithologic contacts and, to a lesser extent, as replacements of the nearby quartzites or sla...
متن کاملGeochemistry, petrology, and mineralization in volcanic rocks located in south Neyshabour, NE Iran
This paper presents the new geochemical isotopes Sr and Nd, and the mineralization data for the south Neyshabour volcanic rocks located in NE Iran. Based on the chemical classifications, the studied rocks are basaltic trachy andesite, trachy andesite, trachyte, and trachy dacite in composition. All the analyzed volcanic rocks display enrichment in light rare earth elements (LREE) relative to th...
متن کاملGeological setting of iron oxide-apatite deposits in theBafq district, central Iran with an emphasis on mineralogical,petrographic, and geochemical study of the Sechahun deposit
The objective of this research is to determine all processes in the magmatic evolution and related hydrothermal activities that created the volcanic rocks and associated ore-forming systems of the Bafq mining district. Several iron oxide-apatite (IOA) deposits were investigated in this area with a focus on the Sechahun ore deposit. The Bafq mining district is well known for hosting significan...
