Lithology identification is an essential fact for delineating uranium-bearing sandstone bodies. A new method provided to delineate bodies by a lithological automatic classification model using machine learning techniques, which could also improve the efficiency of borehole core logging. In this contribution, BP neural network lithology was established optimized gradient descent algorithm based ...

On April 26, 1996, Public Law 104-134 was Chart 1 .-Payment volume, by type of disbursement, fiscal year 1997 enacted, requiring all Federal payments except tax refunds be issued electronically by January 2, 1999, thus beginning a new era in electronic N Federal tax 10.5% funds transfer (EFT). This legislation, the Debt Collection Improvement Act of 1996-part of the Omnibus Consolidated Resciss...

The sandstone-hosted Beverley uranium deposit is located in terrestrial sediments in the Lake Frome basin in the North Flinders Ranges, South Australia. The deposit is 13 km from the U-rich Mesoproterozoic basement of the Mount Painter inlier, which is being uplifted 100 to 200 m above the basin by neotectonic activity that probably initiated in the early Pliocene. The mineralization was deposi...

Sandstone type uranium is the most valuable and has potential for mining among known deposits. In process of forming, hydrolytic migration enrichment require special basin sedimentary environment tectonic background. Therefore, mineralization sandstone deposits certain layering characteristics distribution rules in underground vertical depth space. It important to mine spatial uranium-bearing l...

Based on an analysis of the spatial distribution uranium grade in 338 boreholes a deposit Xinjiang, enrichment and variation ore two stopes are discussed using multifractal theory. The characteristics studied by parameters: scaling exponent mass τ(q), α(q) each sub-set its corresponding fractal dimension f(α), D0 information D1. differences can be quantified well spectrum parameters such as Δα,...

The present paper describes a detailed study on the distribution of radionuclides along Chavara - Neendakara placer deposit, a high background radiation area (HBRA) along the Southwest coast of India (Kerala). Judged from our studies using HPGe gamma spectrometric detector, it becomes evident that Uranium ((238)U), Thorium ((232)Th) and Potassium ((40)K) are the major sources for radioactivity ...

Granite-related uranium ore is an important resource type in China and worldwide. Whether the geochemical theory “U6+ oxidative migration U4+ reductive precipitation” applicable to granite-related mineralization has not been determined. Detailed field petrographic work, as well scanning electron microscopy energy spectrum analysis, are conducted this study analyze relationship between minerals ...
