Earth Science Frontiers > 2009 > 16 > 6 > 129-137

Coastal zones are dynamic areas that are constantly undergoing change in response to a multitude of factors including sea level rise, wave and current patterns, hurricanes and human influences. On ²⁶ th December 2004, huge waves smashed across the shore between Kanyakumari and Ovari. As they crossed the beach, the waves up to 30 feet tall. Many people are dead due to crush and pull to sea...

Modeling the East Asian Climate During the Late Cretaceous (80 Ma)

Junming CHEN, Ping ZHAO, Chengshan WANG, Yongjian HUANG

Earth Science Frontiers > 2009 > 16 > 6 > 226-239

In this study, the East Asian climate during the Late Cretaceous (ca 80 Ma) is examined by using the Community Climate System Model Version 2 (CCSM2) from the National Center for Atmospheric Research (NCAR) and the reconstructed palaeogeographic data. The simulation results indicate that the large-scale prevailing wind directions and pressure systems over East Asia showed a remarkable seasonal variation...

Compositional Characteristics and Geochemical Significance of N-alkanes in Process of Crude Oil Cracking

Xiaoqiang TANG, Guanghui HUANG, Min ZHANG, Jinping HAN

Earth Science Frontiers > 2009 > 16 > 6 > 372-378

The simulation experiments with crude oil samples have been performed in laboratory by using high temperature simulative techniques, and the characteristics of change of compositions have also been analyzed by gcochemical methods in the cracking process. The results indicate that before a large number of gaseous hydrocarbons being generated by cracking of crude oil, the n-alkanes of high molecular...

The Cenozoic Tectonic Evolution of the West Qinling: Constraints on the Uplift and Deformation of the Qinghai–Tibet Plateau

Jinjing GUO, Wenfeng HAN, Xuefeng LI

Earth Science Frontiers > 2009 > 16 > 6 > 215-225

The Cenozoic tectonic and geomorphologic processes of the West Qinling as a part of Qinghai–Tibet plateau could provide some constraints on the uplift and deformation model of the Qinghai–Tibet plateau. On the basis of the analysis for the Cenozoic sedimentary basin and its deformation features, regional fault frameworks and its kinematics, and geomorphologic records, the following preliminary conclusions...

Beach Sediments from Northern South China Sea Suggest High and Oscillating Sea Levels During the Late Holocene

Kefu YU, Tegu CHEN

Earth Science Frontiers > 2009 > 16 > 6 > 138-145

Understanding the history of the late Holocene sea level change is critical for predicting the potential effects of future sea level changes. The coral reef region of the Leizhou Peninsula, in the northern coast of the South China Sea, is an ideal site for studying the Holocene sea level history because of its tectonic stability and the possession of numerous prehistoric sea level indicators. The...

Self-organizing Abiogenic Dissipative Structures in the Geologic History of the Earth

S.L. Shvartsev

Earth Science Frontiers > 2009 > 16 > 6 > 257-275

It is shown that since the appearance of water on the Earth, a stationary disequilibrium-equilibrium water-rock system came into existence. This system is internally inconsistent, which determines its ability to develop continuously in a spontaneous manner for a long geologic time, leading to the formation of principally new mineral phases and geochemical types of water. Within the Earth's crust,...
