Introduction: The rocks of Gusev Crater around the Spirit landing site are mainly olivine-bearing basalts [1-3], and are thought to have crystallized from lava with low viscosity [4]. These rocks are dark in color, vesicular, fine-grained, and have coatings of dust in varying degrees [5, 6]. However, the bedrock outcrops of the Columbia Hills are remarkably different from those near the landing...

Delegations of the various satrapies of the Achaemenid Empire are depicted bringing presents to the king on the reliefs of the Apadana in the palace of Persepolis. Among these presents are two which most likely contained gold. One of the members of the Indian delegation carries a pole over his shoulders from which two baskets are hanging filled with two bags each. From the degree of bending of ...

Introduction: The CONCORDIA micrometeorite collection recovered from central Antarctic snow contains fluffy, fragile particles [1] among which we identified some UltraCarbonaceous Antarctic Micrometeorites (UCAMMs) [2, 3]. UCAMMs are dominated by up to ~ 80 vol% of carbonaceous material that contains small and complex mineral assemblages [2-4]. Their structure and chemical compositions are remi...

Research on material perception has received an increasing amount of attention recently. Clearly, both the visual and the haptic sense play important roles in the perception of materials, yet it is still unclear how both senses compare in material perception tasks. Here, we set out to investigate the degree of correspondence between the visual and the haptic representations of different materia...

Beneath slow-spreading ridges, melt bodies are generally considered to represent ephemeral magma reservoirs filled with crystal mushes. Formation of the oceanic crust requires at least partial extraction melts from these However, collection and processes yet be fully constrained. We investigate olivine gabbros plutonic section recovered IODP Hole U1473A, in Atlantis Bank Oceanic Core Complex (S...

The results of laboratory studies to determine the effect effective stress on permeability sandstone are presented. During test, samples were subjected a stepwise increase or decrease (at constant pore pressure) in specified step. values rock at different determined, and influence grain size reservoir matrix character change coefficient was also established. observed with an stress. It found th...

The design of geotextile containers for dewatering applications typically requires hydraulic compatibility between the geotextile and the confined fill material. Ideally, a geotextile container must successfully retain the solid phase of the fill material and must not be clogged during the dewatering process. This becomes difficult to achieve when the fill material is fine grained and the pore ...
