In the Ordos Basin, Chang 81, a Member of Yanchang Formation, features development braided river thin-bedded tight sandstones. These sandstones constitute one main production layers oil and gas in Formation within basin. This study integrates data from core samples, drilling, seismic information to identify 81 at Daijiaping, using method constrained correlation between waveform facies. approach...

Comparisons of paleofaunas from different facies are often hampered by the uncertainty in the variation of taphonomic processes biasing the paleoecological parameters of interest. By examining the taphonomic patterns exhibited by different facies in the same stratigraphic interval and area, it is possible to quantify this variation, and assess inter-facies comparability. The fossil assemblages ...

Interpretations of faunal assemblages from the late Miocene Mpesida Beds in the Tugen Hills of the Central Kenyan Rift Valley have figured prominently in discussions of faunal turnover and establishment of the modern East African communities. These faunal changes have important implications for the divergence of the human lineage from the African apes ca. 8-5 Ma. While fossil material recovered...

Introduction: Recent reexamination of the fan-shaped deposits on the NW flanks of the Tharsis Montes and Olympus Mons has revived earlier interpretations [e.g., 13] that these deposits could have a glacial origin. New spacecraft data and improved understanding of cold-base glacier behavior has led to the interpretation that these features are the depositional remains of cold-based tropical moun...

This paper presents for the first time a detailed study on information content of X-band single-pass interferometric spaceborne SAR data with respect to snow facies characterization. An approach for classifying different snow facies of the Greenland Ice Sheet by exploiting X-band TanDEM-X interferometric synthetic aperture radar acquisitions is firstly detailed. Large-scale mosaics of radar bac...

This chapter presents the Late Quaternary neo-tectonic movement in the Pearl River Delta (PRD) region of China and its effects on the coastal sedimentary environment. Taking the Xilin Hill fault as the example, we have explained the reason of the PRD formation, inferred its interactions with local/regional climate and sea-level changes, and analyzed the evolution of the PRD formation and its co...

This research successfully extends a deterministic, physically-based inverse theory that is capable of simultaneous parameter and boundary condition estimation to uncertainty quantification in inverting steady-state groundwater flow in a two-dimensional aquifer with facies heterogeneity. Using facies and dynamic flow measurements sampled at wells as observations, a stochastic subsurface data in...

Introduction: The strong geomorphic similarities between lobate deposits 1) on the northwest flank of the Tharsis Montes [1,2] and 2) along the dichotomy boundary between 30° and 50° [3] with terrestrial cold-based glaciers and glacial deposits has led to hypotheses for geologically recent (Amazonian-age) low and mid-latitude glaciation on Mars [1,4]. The key to these studies has been to identi...

The Main Glauconite Bed (MGB) is a pelleted greensand located at Stone City Bluff on the south bank of the Brazos River in Burleson County, Texas. It was deposited during the Middle Eocene regional transgression on the Texas Gulf Coastal Plain. Stratigraphically it lies in the upper Stone City Member, Crockett Formation, Claiborne Group. Its mineralogy and geochemistry were examined in detail, ...
