Welcome to the Geology, Geophysics, and Geochemistry Science Center (GGGSC) located in Lakewood, Colorado on the Denver Federal Center. At GGGSC, we apply expertise in geology, geophysics, and geochemistry to interdisciplinary efforts in support of the USGS mission to address the Nation’s important earth science issues, with an emphasis on mineral resources. The Archean crust in the Nuuk region of SW Greenland ranges in age from Ga tonalite to Ga granite [1,2].Interspersed with such evolved continental crust, are scattered enclaves of both mafic and ultramafic rocks, which range in size from decimeter to kilometer scale ().These remnants of older crustal components in the Archean continental crust are dominated by mafic metavolcanic rocks Author: Laura Whyatt, Stefan Peters, Andreas Pack, Christopher L. Kirkland, Tonci Balic-Zunic, Kristoffer Sz.
Abstract. The aims of this review chapter are to (i) summarize the distribution of halogens in different fluid (surficial, formation and crystalline shield waters, metamorphic, magmatic-hydrothermal-geothermal) and solid (oceanic and continental crust, mantle and core) domains of the Earth, and various extra-terrestrial materials and bodies (meteorites, planets Cited by: 7.

Compare and contrast the mineral composition of granitic, basaltic, intermediate, and ultramafic igneous rocks. Granitic or felsic rocks: composed of quartz and K-feldspar (light) and 10% of biotite and amphibole (dark). Soil Geochemical Survey Click to Enlarge. When Hard Creek geologists noticed strongly anomalous analytical results for copper, nickel, platinum and palladium in samples from several reconnaissance soil lines, the decision was made to cover the Turnagain ultramafic with a systematic soil survey.

Details of the mineralogy of UM-2 and UM-4 are given in Geological Survey of Canada Paper"Three geochemical standards of sulphide-bearing ultramafic rock: UM-1, UM-2, and UM-4".
The following table by E.M. Cameron provides values for the major and minor elements; they are intended for information purposes only. Chemical analyses of ultramafic rock standards: UM-1, UM-2, UM Chem.

The above three ultramafic samples are a useful addition to existing rock standards as they bridge as well as augment the available ranges of composi- tions.

Geochemical rock data obtained by major- and trace-element analyses and geological studies of nickel sulphide mineralization associated with ultramafic rocks and the sedi- mentary pyrite mineralization at Lake Yindarlgooda in the Eastern Goldfields greenstone belt, Western Australia, led to following results: (1) The Morelands Formation is the most favourable association for nickel sulphide mineralization associated with ultramafic rocks Cited by: 1.
The Archaean (c. Ma) ultramafic rocks in eastern Sierra Leone cut basalt lavas and are mostly olivine-rich cumulates either iron-rich (Fo85_86) and derived from a basaltic or picritic parent, or more magnesian (F_93) derived from an ultramafic melt with c.
% : Hugh Rollinson. Geology of the Duke Island Complex  The ultramafic rock types of the Duke Island Complex occur in two major outcrop areas; one at the center of the island, called the Hall Cove area (due to the close proximity of the Hall Cove sea inlet) and another at the southeastern part of the island, called the Judd Harbor area.
The geochemical behavior of ultramafic waste rocks and the effect of carbon sequestration by these waste rocks on the water drainage quality were investigated using laboratory-scale kinetic column tests on samples from the Dumont Nickel Project (RNC Minerals, QC, Canada).
The test results demonstrated that atmospheric CO2 dissolution induced the Cited by: 2. chromium geochemistry in serpentinized ultramafic rocks and serpentine soils from the franciscan complex of california christopher oze*†, scott fendorf, dennis k.

Briefly, – mg of rock powder was digested either in concentrated HF‐HNO 3 on a hotplate at °C in screw‐top Savillex ® beakers for basaltic rocks, or in concentrated HF‐HNO 3 ‐HClO 4 at °C in steel‐jacketed high‐pressure PTFE bombs for all other rock.
These meta-sedimentary rocks typically have three times the Zn concentration ( ppm) to that of Cu ( ppm). However, because nickel sulphides have a greater concentration of Cu than Zn, the Cu: Zn ratio can assist in discriminating Ni sulphide-bearing zones from those with no Ni by: Buy PETROLOGY AND GEOCHEMISTRY OF MAFIC AND ULTRAMAFIC ROCKS FROM THE NORTHERN BIGHORN MOUNTAINS, WYOMING on.
We present mineralogical, petrological and geochemical data to constrain the origin of the Harzburg mafic–ultramafic intrusion. The intrusion is composed mainly of mafic rocks ranging from gabbronorite to quartz diorite.
Ultramafic rocks are very rare in Cited by: Their copper contents range from a few to several thousand parts per million and in seven of the samples copper sulphides (bornite and chalcopyrite) were posi- tively identified.
Zinc values are relatively uniform, ranging from 18 to 44 ppm.

Mineralogical and geochemical data of hydrothermal sediments collected from the Saldanha site are presented.

Ultramafic rocks tend to weather more rapidly than other lithologic units and may form depressions under humid climates, so that in many places (e.g., Mt.
Keith) they have been buried by sediments during and after this weathering. Nevertheless, local topographic inversion is a feature of some terrain underlain by ultramafic rocks. Bulk chemical analyses indicate that the ultramafic rocks contain ± wt percent SiO 2, generally about 30 wt percent MgO, and AI 2 O 3 in excess of 5 wt percent.
