Abstract Nickel sulfide deposits occur in ultramafic rocks the Daxinganling area, China; however, prospectivity of these has received little attention. This study transformed rasterized regional 1:200,000 geochemical data into spectral-like and then used hyperspectral tools spectral angle mapper (SAM) to classify possible lithologies multirange feature fitting (MRSFF) method prospective areas t...

Introduction Volcanism on Venus has produced a rich array of volcanic landforms [1], which in turn suggests a broad range of magma production and differentiation environments. In the next decade, it is possible that one or more landers associated with New Frontiers or Flagship class missions to Venus will provide new geochemical observations of the Venus surface. The goal of this work is to mak...

GeoChip is a comprehensive functional gene array that targets key functional genes involved in the geochemical cycling of N, C, and P, sulfate reduction, metal resistance and reduction, and contaminant degradation. Studies have shown the GeoChip to be a sensitive, specific, and high-throughput tool for microbial community analysis that has the power to link geochemical processes with microbial ...

Geochemical studies and surveys conducted by the Geological Survey of Canada have provided considerable information about the natural geochemical variations in glacial drift, lake sediments, and lake waters in south-central District of Keewatin. In addition to their intended contribution to mineral exploration, these activities yielded much basic background data that may be applied to the plann...

Biomineralization marks one of the most significant evolutionary milestones among the Eukarya, but its roots in the fossil record remain obscure. We report crystallographic and geochemical evidence for controlled eukaryotic biomineralization in Neoproterozoic scale microfossils from the Fifteenmile Group of Yukon, Canada. High-resolution transmission electron microscopy reveals that the microfo...

We welcome the opportunity to respond to the Comment of Bence et al. (2000) regarding the suitability of the new geochemical parameter we have introduced. Part of their comment, however, addresses issues either not directly related to our paper, or issues published elsewhere. The lengthy comment seems a disproportionate reaction to what was a paper of limited scope, simply introducing one new g...

Knowledge-and data-driven approaches are two major methods used to integrate various evidential maps for mineral prospectivity mapping (MPM). Geological maps, geochemical samples and data from known gold deposits were collected in the western Junggar area, Xinjiang Province. The geological and a spatial database for geological and mineral occurrences were constructed for the studied region. A w...
