The airborne hyper-spectral survey system CASI/SASI, which has an integrated for gathering both image spectral data, is at the cutting edge developments in remote-sensing field. It can be used to directly identify surface objects based on diagnostic characteristics. In this paper, CASI/SASI were Huaniushan gold-silver-lead-zinc ore district–Gansu produce a lithologic map, altered minerals, and ...

Deep continental crustal structures are enigmatic due to lack of direct exposures and limited tools investigate them remotely. Seismic waves can sample these rocks, but most seismic methods focus on coarse while laboratory measurements concentrate crystal-scale rock properties, little work has been conducted bridge this interpretation gap. In some places, geologic maps crystalline basement prov...

Seismic imaging, popularly known as tomography, borrowing the term from medical sciences, produces the raster image of the internal structure by combining information from a set of projections obtained at different viewing angles. To engineer high resolution and accurate solutions to mining problems, seismic traveltime tomography can yield a high resolution image of the subsurface to provide in...

Abstract Weathering of silicate rocks at a planetary surface can draw down CO 2 from the atmosphere for eventual burial and long-term storage in interior. This process is thought to provide essential negative feedback carbonate-silicate cycle (carbon cycle) maintain clement climates on Earth potentially similar temperate exoplanets. We implement thermodynamics determine weathering rates as func...

We use a classic locale for geology education in the White Mountains, CA, to demonstrate novel approach using imaging spectroscopy (hyperspectral imaging) generate base maps purpose of geologic mapping. The produced this fashion are complementary to, but distinct from, mineral abundance. synthesizes two concepts data analysis: spectral mixture residual and joint characterization. First, uses li...

“Danxia landform” is a landform type originally defined in China, characterized by red-colored sandstones and steep cliffs, and developed through long-term erosion. In recent years, Danxia landforms have been receiving international attention, and six examples in China became a UNESCO World Natural Heritage in 2010. However, morphometric studies of Danxia landforms in China have been very limit...
