The engineering properties of the lunar regolith reflect aspects of the original parent rock and the consequences of hypervelocity meteor bombardment. Compared to the Earth the geologic nature of the lunar regolith is quite distinct. On scales relevant to machinery, heterogeneity with respect to size and composition is much higher. But the total range in composition is much more restricted. Bot...

various geological units in an area often exhibit different magnetic properties. due to this distinction in magnetic properties of the geological units, a correlation between the type of a geological unit and its magnetic response can be established. to determine the lateral and vertical extents of geological units from the magnetic data in a survey area, a number of filters for processing magn...

We tested an efficient, easily and economically manufactured wind-transported particle collector of our own design, called a multidirectional trap (MDt), on fine-tilled Anthrosols. Results from the logs nine vaned masts, each with four MDt collectors at different heights, showed clear predominance northeast south winds. After analyzing sediment transport rates their balance, we found that sedim...

the southeastern part of turkey is quite rich, fertile and mature in terms of hydrocarbonseepages. while the use of the related sources meet the energy demand, it damages the environment and humanhealth. in this study, several geochemical methods were applied to analyze the hydrocarbon sepage samplesobtained from seven towns in the province of adiyaman where is very close to the oil production ...

two dimensional single frequency scalar vlf data modeling has been studied in this research. vlf method is one of the electromagnetic investigation methods. radio frequency waves are used for investigation of conductive deposits (paal, 1968). synthetic modeling and inversion of single frequency and multiple frequencies of vlf signals was done by oskooi (2004) for two dimensional simple structur...

This chapter will summarize the historical development of geology and in particular the development of the modern uniformitarian view of the geological record and the millions-of-years time-scale. The important proponents of old-earth thinking (including Werner, Smith, Hutton, Cuvier, and Lyell) along with some of the opponents of this view as it was developing (the scriptural geologists) will ...

background and objectives : zeolite is a group of anionic hydrated aluminosilicates with a tridimensional structure which has great implications in remediation of water, sediment and soil resources. the present research aims at physicochemical investigation, clay mineralogy and micromorphology of soils along rafsanjan-sarcheshmeh lithotoposequence, southeastern iran. materials and methods: the ...

Tazhong Oil Field located in the center of Tarim Basin is one of the greatest discoveries during the petroleum exploration in Tarim Basin. The course of many years for hydrocarbon exploration and development has proved that there existed a much larger ancient reservoir than present-day reservoir and residual oil section below present WOC is of obvious characteristics of water displacement. Stud...

The accretion of the Indian subcontinent to Eurasia triggered a massive faunal and floral exchange, with Gondwanan taxa entering into Asia and vice versa. The traditional view on the Indian-Asian collision assumes contact of the continental plates during the Early Eocene. Many biogeographic studies rely on this assumption. However, the exact mode and timing of this geological event is still und...
