Introduction: A TES spectral study of low albedo (LA) deposits within the Amazonis Planitia of Mars revealed that the derived bulk composition of these deposits contain very low silica contents (Fig. 1), classifying some of the deposits as foidites [1]. A foidite is an igneous rock in which feldspathoid minerals constitute ≥60% of the light-colored mineralogy; it is the inclusion of feldspathoi...

Feldspar (alkali feldspar and plagioclases) in recent years feldspathoid minerals are used as raw materials the ceramic-glass industries. The igneous rocks such granite, syenite foid which mainly contain these have potential to be materials. Some inclusions within feldspatic affect extremely negatively desired values for material. In this study, effective processes alteration of Özvatan syenite...

The article provides a brief overview of the problems copper production in Kazakhstan. It is shown that main current problem copper-smelting involvement low-grade ores complex mineral composition. Existing technologies are focused on processing ore with higher content, accordingly, it necessary to adjust existing enrichment and smelting technologies. To determine composition some samples promis...

In this paper we classify the range of feldspathic igneous rocks using five geochemical variables: the FeO/(FeOþMgO) ratio or Fe-index, the modified alkali^lime index, the aluminum-saturation index, the alkalinity index, and the feldspathoid silica-saturation index.The Fe-index distinguishes between melts that have undergone extensive iron enrichment during differentiation from those that have ...

I will start this treatise with a history of two major themes in data integration. In my opinion, the topic began with the major retailers in the 1990s consolidating their sales data into a data warehouse. To do this they needed to extract data from in-store sales systems, transform it into a predefined common representation (think of this as a global schema), and then load it into a data wareh...

In order to automate the scooping task, it is desirable that the resistive force acting on the bucket be obtained before the scooping is performed. The objective of this study is to derive theoretically the resistive forces acting on the bucket during scooping of piled rock fragments. First, the changes in the shape of the rock pile due to the penetration of it by the bucket are modeled. Based ...

Once segmentation of 3D surface data of a rock pile has been performed, the next task is to determine the visibility of the surface rocks. A region boundary-following algorithm that accommodates irregularly spaced 3D coordinate data is presented for determining this visibility. We examine 3D surface segmentations of laboratory rock piles and determine which regions in the segmentation correspon...
