In this paper, we aim to achieve two specific objectives. The first one is to examine the applicability of wavelet neural network (WNN) technique in ore grade estimation, which is based on integration between wavelet theory and Artificial Neural Network (ANN). Different wavelets are applied as activation functions to estimate Cu grade of borehole data in the hypogene zone of porphyry ore deposi...

Chlorite flakes, as a product of alteration of biotite, the dominant ferromagnesian mineral in the Paleozoic granitic rocks of the Canadian Appalachians, have been analyzed by electron microprobe for major elements and by 57Fe M?ssbauer spectroscopy for the coordination and oxidation state of Fe. Comparison of M?ssbauer Fe3+/Fe ratios obtained from chlorite and its host biotite indicates that c...

objective: in the colophon of every manuscript there is a date which indicates of the time when it has been written. sometimes these colophon dates change into another date through a slight manipulation. sometimes some dates have the potential of changing into another date, either because of passage of time or due to the scribe’s method of writing. this issue creates a problem for cataloguers, ...

Introduction: With the recent return of remote sensing evidence for aqueous alteration on Mars in the form of evaporates and other secondary minerals (MERs [e.g., 1] and Mars Express [e.g., 2]), understanding the differences between weathering processes on Mars and Earth becomes imperative. Martian meteorites provide the only available source of detailed geochemical analyses of Martian material...

In this paper, we aim to achieve two specific objectives. The first one is to examine the applicability of the Artificial Neural Networks (ANNs) technique in ore grade estimation. Different training algorithms and numbers of hidden neurons are applied to estimate Cu grade of borehole data in the hypogene zone of porphyry copper-gold deposit, Masjed-Daghi, East Azerbaijan Province (Iran). The ef...

Abstract: The Urumieh-Dokhtar Magmatic Belt (UDMB) is the host of many Iranian Cu porphyry deposits. Southern part of this belt, in the range of geological Jebal barez, has been less investigated because of the mountainous and rough topography and also some security confrontation. Porphyry deposits are associated with hydrothermal alteration zones can be mapped using remote sensing data such as...

INTRODUCTION The authors present IR spectra (0.9–2.5 μm) and narrowband photometry (3.0–3.5 μm) for low-albedo asteroids Ceres, Pallas, and Bamberga. The authors compare the major mineral absorption features to those found in primary carbonaceous chondrite matrix material (CCMM) and secondary alteration products. The observed differences between spectral reflectances between the three C-type as...

Game environments are becoming more and more mutable from the actions of both Players and Non Player Characters (NPCs). However, current generation AI agents do not take advantage of the tactical abilities these mutable worlds provide. We propose a method to make the game agents aware of the mutability of the world by extending their repertoire of abilities to include world alteration commands ...
