This document provides a summary of field activities conducted as part of a 9-day geology field course in June 2014. Students visited 6 coastal sites on Vashon Island, Maury Island, and the northeastern Olympic Peninsula to conduct geological mapping, sample collection, and analysis. Techniques used included optically stimulated luminescence dating, radiocarbon dating, coring, discontinuity mapping, provenance analysis, soil classification, and GPS surveying. The document describes the locations visited and tasks conducted at each site to achieve the course objectives of characterizing coastal deposits and processes.
What is an ore?, Ore deposit environments, Formation of Mineral Deposits, Endogenous (Internal) processes, Exogenous (Surficial) processes, Types of Sedimentary Rocks, Mineral Deposits Associated with Sedimentary Process, physical processes of ore deposit formation in the surficial realm, Erosion, weathering , transportation, sorting, Precipitation, Depositional Environments, Deposits formed by Weathering, Deposits formed by Sediment, Resources from the Sedimentary Environments
6. Supergene and secondary enrichment deposits.pptxAmanuelBuzuna1
The document discusses supergene and secondary enrichment deposits that form near the Earth's surface through descending meteoric waters. Different zones can form at varying depths, including a gossan cap, leached zone, oxidized zone, water table, and enriched zone. In the oxidized zone above the water table, secondary minerals form through reactions between solutions and primary minerals. Below the water table in the reducing enriched zone, supergene sulfides like covellite form. This process concentrates metals by moving ions from the leached to enriched zones. Primary minerals like chalcopyrite can alter to secondary minerals like bornite or covellite. Residual deposits form through chemical weathering that concentrates elements by leaching others from the bedrock
Geologists and geophysicists work together using various methods like collecting rock samples, studying rock properties, and surveying magnetic and gravity fields to understand the geology of an area. This informs decisions about whether to drill exploratory wells. Petroleum exploration uses direct observations of natural oil seeps. It also uses geological mapping and analysis of subsurface data from wells. Geophysical methods measure gravity, magnetic, and seismic readings to identify underground structures that may indicate oil and gas reservoirs. Together, these techniques provide information to evaluate a site's potential for commercial petroleum deposits.
