Imaging spectroscopy is a widely used tool in mineral exploration today where exploration companies offer the full service package to their clients: (data acquisition, preprocessing and product delivery). These exploration projects rely mainly on airborne imaging spectrometers such as Hymap, AISA or HySpex. This data is usually scarce and expensive and may not be available to academic research....

lag is a general term applied to coarse grained (> 2 mm), hard, but partially weathered rockfragments, which are concentrated at the surface through attrition of finer materials. based on morphology,mineralogy and the origin of lag from the cobar region of australia, lag may be conveniently grouped intothree broad morpho-mineralogical categories; (a) those with a rough, blocky, lithic morpholog...

Several technical challenges are related to data collection, inverse modeling, model fusion, and integrated interpretations in the exploration of geophysics. A fundamental problem geophysical interpretation is proper geological understanding multiple inverted physical property images. Tackling this requires high-dimensional techniques for extracting information from modeled In study, we develop...

in this research work, the frequency domain (fd) of surface geochemical data was analyzed to decompose the complex geochemical patterns related to different depths of the mineral deposit. in order to predict the variation in mineralization in the depth and identify the deep geochemical anomalies and blind mineralization using the surface geochemical data for the dalli cu-au porphyry deposit, a ...

A study was conducted to investigate the existing system of fry trade and different problems and prospects associated with this enterprise in Jessore district. A total of 82 hatchery operators and nursery owners were interviewed using a structured questionnaire. In the study period 4211.5 kg hatchling were produced in 85 hatcheries in this area of which 80% were reared in the same area. Average...
