geochemically

Other forms of sulfur are important geochemically, as well.

There are only a few thousand mineral species and 83 geochemically stable chemical elements combine to form them.

These are geochemically distinct from the later volcanism, as they contain amphiboles.

Some of the soils are geochemically very unusual.

The Moon is a differentiated body: it has a geochemically distinct crust, mantle, and core.

Therefore, it is classified geochemically as alkaline rock.

In this case the fossil consists of original material, albeit in a geochemically altered state.

They are formed, both geochemically and in the laboratory, by the reaction of hydrogen sulfide with metal salts.

Although Champagne Pool is geochemically well characterised, few studies have addressed its role as a potential habitat for microbial life forms.

(An extremophile is an organism that can thrive in a physically or geochemically extreme condition that would be detrimental to most life on Earth.)

Tephrochronology is a method for geochemical correlation of unknown volcanic ash (tephra) to geochemically fingerprinted, dated tephra.

Remote sensing techniques, specifically hyperspectral imaging, have been used to detect hydrocarbon microseepages using the spectral signature of geochemically altered soils and vegetation.

The granites geochemically include calc-alkaline granites with alkaline, meta-aluminous to peraluminous more abundant and monzogranites granites.

Geochemically, the TTGs are typically low- to medium-K (potassium), metaluminous I-type granites.

"The granites are petrologically and geochemically similar to Phanerozoic A-type granitoids, presumably emplaced into noncompressive or extensional environments.

Basalts found at oceanic islands are geochemically distinct from those found at mid-ocean ridges and volcanoes associated with subduction zones (island arc basalts).

According to the petrologist Adrian C. Hutton of the University of Wollongong, oil shales are not "geological nor geochemically distinctive rock but rather 'economic' term."

Items that are usually used in a piercing point study include large geologic formations or other rock units that can be matched either stratigraphically, geochemically, or by age dating.

Ocean-floor basalt sequences are exclusively tholeiitic, and are geochemically similar to modern N- and E-type MORBs erupted in back-arc basins.

However, because it does not blend geochemically with those elements that constitute the majority of the crustal mass, mercury ores can be extraordinarily concentrated considering the element's abundance in ordinary rock.

As the Pliocene-Pleistocene sands were considered geochemically immature and wells drilled to the north of Block 330 discovered natural gas, Pennzoil expected to discover a natural gas not oil.

Geochemically, carbonatites are dominated by incompatible elements (Ba, Cs, Rb) and depletions in compatible elements (Hf, Zr, Ti).

All six of the Apollo missions on which samples were collected landed in the central nearside of the Moon, an area that has subsequently been shown to be geochemically anomalous by the Lunar Prospector mission.

However, the Rubislaw Quarry, stone from which has been widely used throughout the area, is located in the Aberdeen granite, which is less geochemically evolved and has a lower uranium content than the other granites.

Geochemically, the Kambalda Ratio Ni:Cr/Cu:Zn identifies areas of enriched Ni, Cu and depleted Cr and Zn.
