The Textures of Rocks in the Earth’s Deep Interior: Part I. Understanding Anisotropy and Textures in Earth Materials
Preferred orientation of crystallites (or texture) is an intrinsic feature of metals, ceramics, polymers, and rocks and has an influence on physical properties such as strength, electrical conductivity, wave propagation, particularly the anisotropy of properties. The directional characteristics of many polycrystalline materials were first recognized not in metals but in rocks and were described...
متن کاملMethane and carbon at equilibrium in source rocks
Methane in source rocks may not exist exclusively as free gas. It could exist in equilibrium with carbon and higher hydrocarbons: CH4 + C < = > Hydrocarbon. Three lines of evidence support this possibility. 1) Shales ingest gas in amounts and selectivities consistent with gas-carbon equilibrium. There is a 50% increase in solid hydrocarbon mass when Fayetteville Shale is exposed to methane (450...
متن کاملNon–gaussian Fluctuations from Textures
One of the most powerful tools to probe the existence of cosmic defects in the early universe is through the Cosmic Microwave Background (CMB) radiation. It is well known that computations with causal sources are more involved than the adiabatic counterparts based on inflation, and this fact has in part hampered the development of fine detailed predictions. Analytical modeling, while necessaril...
متن کاملTextures of the soils and rocks at Gusev Crater from Spirit's Microscopic Imager.
The Microscopic Imager on the Spirit rover analyzed the textures of the soil and rocks at Gusev crater on Mars at a resolution of 100 micrometers. Weakly bound agglomerates of dust are present in the soil near the Columbia Memorial Station. Some of the brushed or abraded rock surfaces show igneous textures and evidence for alteration rinds, coatings, and veins consistent with secondary minerali...
متن کاملData mining on non-homogenous textures
Clustering of the texture images is a demanding part of multimedia database mining. Most of the natural textures are non-homogenous in terms of color and textural properties. In many cases, there is a need for a system that is able to divide the non-homogenous texture images into visually similar clusters. In this paper, we introduce a new method for this purpose. In our clustering technique, t...
