Objectives: Our two primary objectives are to use Miniature Thermal Emission Spectrometer (Mini-TES) data to determine the mineralogy of the alteration coating on the target Mazatzal [e.g., 1], and to determine if there is mineralogical evidence for sulfate-producing alteration of Adirondack-class rocks. Secondary objectives include identifying any Adirondack-class exotics on the plains or on t...

The metamorphic sole rocks at the base of mantle peridotites from the Mersin ophiolite consist of amphibolites and metasedimentary lithologies. Mineral parageneses in the metamorphic sole rocks exhibit amphibolite and greenschist facies assemblages. Geothermobarometric studies based on mineral assemblages and chemical compositions of minerals indicate that average metamorphic temperature during...

The island of Syros consists largely of possibly-repeated sequences of glaucophane-bearing calcareous schists, mafic schists, dolomite marbles, and calcite marbles containing abundant aragonite pseudomorphs (Dixon, 1969; Hecht, 1984). Several discrete, fault-bounded packages of blueschist/eclogite-facies mafic rocks with minor serpentinite are also found on the island. Although the mafic rocks ...

Background: Robotic arms on landed spacecraft are typically designed to either (a) retrieve surface samples for analyses by the main spacecraft or (b), bring a mobile instrument package into contact with surface components. Yet the engineering data returned by a robotic arm while conducting these science support operations can themselves be used to investigate the physical properties of surface...

Abstract Polycrystalline Diamond Compact (PDC) bit has been used widely in drilling operations since a long time ago. However, the utilization of this Indonesia’s geothermal just recently started 2016, thanks to rapid development PDC cutter grades and shapes last decade. Prior that, operation relied on Tungsten Carbide Insert (TCI) drill hard formations. The crushing action insert is very durab...

The aim of the paper is to develop a fully 3D simulation technique for rockfall dynamics taking rock shape into account and using the state-of-the-art methods of multibody dynamics and nonsmooth contact dynamics. The rockfall simulation technique is based on the nonsmooth contact dynamics method with hard contact laws. The rock is modeled as an arbitrary convex polyhedron and the terrain model ...

The paper describes a novel method of drilling into hard non-conductive materials by localized microwave energy (US patent 6,114,676). The Microwave Drill implementation may utilize a conventional 2.45GHz magnetron, to form a portable and relatively simple drilling tool. The drilling head consists of a coaxial guide and a near-field concentrator. The latter focuses the microwave radiation into ...

Analysing American society and finding little hope for it has almost become a 'favourite sport' for sociologists. Another book on this theme illustrates the strongly-felt and yet somehow 'manufactured' crisis of conscience in the USA.

A brief summary of the importance of the electrical resistivity of rocks in geothermal exploration is given as well as some of its is main relationships with some of the characteristics of geothermal reservoirs. Special emphasis is on the resistivity of rocks in high temperature geothermal fields where the dominant factor is the hydrothermal mineral alteration and how it relates to temperature....
