ALLANITE-(Ce) FROM THE EOCENE CASTO GRANITE, IDAHO: RESPONSE TO HYDROTHERMAL ALTERATION
The response of allanite-(Ce) in the Eocene Casto granite of Idaho to hydrothermal activity has been investigated. Unaltered, igneous allanite from the Casto pluton is characterized by a narrow range of compositional variation, with little or no zoning. A representative empirical formula, based on the composition of the least-altered grain, is: (REE0.83Ca1.07Th0.04Mn0.06) (Ti0.11 Mg0.04Fe0.99Fe...
متن کاملOrganic Geochemical Biosignatures in Alkaline Hydrothermal Ecosystems
The 13C content of microbial products are controlled by many factors, including the 13C content of the growth substrate, growth rate, the flux of carbon through various parts of the biochemical network, and the isotopic fractionation imposed by the enzymes of that network. We analyzed the 13C content of products of the methanogen Methanosarcina barkeri and found that fractionation varied strong...
متن کاملModeling Low-Temperature Geochemical Processes
A model takes on the quality of theory when it abstracts from raw data the facts that its inventor perceives to be fundamental and controlling, and puts these into relation to each other in ways that were not understood before—thereby generating predictions of surprising new facts. Geochemical modeling has become a popular and useful tool for a wide number of applications from research on the f...
متن کاملThe relation between iron-formation and low temperature hydrothermal alteration in an Archean volcanic environment
The uppermost section of the Hunter Mine group (HMG) (2728 Ma), a bimodal volcanic complex in the Abitibi greenstone belt, contains both oxide and carbonate facies banded iron-formation (BIF). This paper explores the relationship between volcanic activity and the development of the two types of iron-formation. The oxide facies, represented by chert-jasper-magnetite iron-formation is widespread ...
متن کاملIdentifying Hydrothermal Alteration: Geochemical Particulars based on Lithogeochemical Data from the Kahang Cu Porphyry Deposit, Central Iran
Kahang Cu Porphyry deposit is situated in the central part of a major Iranian magmatic belt, Urumieh-Dokhtar, in central Iran.There are several sub-volcanic stocks (e.g., porphyric granitoids rocks, quartz monzonite, diorite and monzodiorite-monzogranite)within Eocene volcanic and pyroclastic rocks consisting of basaltic, trachy-andesite and dacitic rocks. Hydrothermal alterations at the Kahang...
