Hydrocarbon weathering color age dating

Selected alteration minerals present in the core samples, such as clay minerals and carbonates, were mapped.The “pseudo-modal” mineralogical composition for each sample was determined.The purpose of this study is to evaluate the utility of hyperspectral mapping of alteration minerals in drill core samples using the Hy Spex SWIR-320m hyperspectral camera that covers the 1300–2500 nm (SWIR) spectral range.A series of representative samples, including pegmatite, pelitic gneiss, and sandstone, from the area around the Cigar Lake uranium deposit (Athabasca Basin, Saskatchewan, Canada) were analyzed by SWIR reflectance spectroscopy and optical microscopy.Uptake of carbon dioxide by the oceans is not a harmful phenomenon , but excess of it leads to a reduction in p H thereby altering the fundamental seawater chemistry, commonly known as ocean acidification ....[tags: Dissolution Rates, Acidity] - Picture smog filled cities being pollution free, while producing clean biofuel and oxygen.alkaline - Term pertaining to a highly basic, as opposed to acidic, substance.For example, hydroxide or carbonate of sodium or potassium.

Classification Two classification schemes are in common use by those who work on carbonate rocks.In mineral exploration, the search for geophysical, geochemical, and mineralogical pathfinders is of critical importance, and many techniques have been used to detect the presence of mineralization and related host-rock alteration.In the case of unconformity-type uranium deposits that are spatially-linked to unconformities between sedimentary basin and underlying basement rocks, hydrothermal fluid-rock interactions produced extended alteration envelopes which are used to target mineralization and are therefore important guides for uranium exploration.Geological analysis relies mainly on chemistry, physics and mathematics. a'a' lava - basaltic lava characterized by a rough or rubbly surface composed of broken lava blocks called clinker.A-horizon - The uppermost layer of a soil, containing organic material and leached minerals.The mineral maps highlight the mineralogy and the main petrographic textures such as foliation, bedding, veins, and the geometry of pervasive alteration.
