Tectonic Environment

This study presents some research results on the relationship between the geological environment of the surface layer and the level of modern tectonic activity in the sea waters of the Hoi An - Cua Dai area based on the interpretation of high-resolution shallow seismic data combined with the surface sediments’ grainsize analysis and other available data sources. The results show that the surface geological environment in the coastal waters North of the Thu Bon river fault is influenced by modern tectonic activities, believed to be a part of causing geological catastrophic events.

Depositional environments in areas located near sea level are vulnerable to even subtle changes in both tectonism, climate and eustatic sea level. Sorting out mechanisms behind depositional changes in inner shelf-margins and epeiric seas is therefore far from straight forward. The epeiric Malay-Tho Chu Basin, located in the shallow Gulf of Thailand offshore Vietnam, contains a thick uppermost Oligocene to Recent post-rift succession.

The southern part of the Western Anatolia Extensional Province is governed by E-W-trending horst-graben systems and NW-SE-oriented active faults. The NW-striking Yatağan Fault is characterised by an almost pure normal sense of motion with a minor dextral strike slip component. Although the settlements within the area have been affected by several earthquake events since ancient times (~2000 BCE), the earthquake potential and history of the Yatağan Fault has remained unknown until a few years ago.

Varto and the surrounding region have important geothermal fields, developing in strike-slip tectonic setting in East Anatolia, which resulted from the collision of the Arabian and Eurasian plates. The main structural elements in the area are the NE-trending sinistral and NW-trending dextral strike-slip fault segments and N-S trending extension zones. In order to determine fault-controlled geothermal circulation, it is very important to fully characterize the structural elements in these complex environments.

Benxi area, Northeastern China, is the main distribution area of Archean BIF-hosted iron deposits in China. I n this area, Nanfen iron deposit is well known as the largest open-pit iron deposit not only in China but also in Asia. So far, the tectonic nature during Archean BIF formation period in Benxi area has been long disputed and the tectonic setting of Nanfen BIF had not been found. In this study, the geochemical characters of chlorite amphibolites closely associated with BIF have been investigated for the tectonic environment of Nanfen BIF.

Integrated mineralogical and geochemical methods are utilized to investigate the provenance, paleoweathering, and depositional setting of shale from the Lower Triassic Beduh Formation in the Northern Thrust Zone, Iraq. The ~64-m-thick Beduh Formation consists of calcareous shale and marl intercalations with thin calcareous sandstone interbeds.

The tectonic events of the past three years—September 11 and Operation Enduring Freedom, the global war on terrorism, and the war in Iraq and its aftermath—have dramatically affected the Muslim world and attitudes toward the United States. However, some of the dynamics that are influencing the environment in Muslim countries are also the product of trends that have been at work for many decades.

Many have endeavored to make our outdoor environment cleaner and safer. The learning process that occurred showed us the limitations of our planet and also the sustainability of our ecosystem if given a chance. As a community, we learned about the water, the soil, and the air. We learned about the underground river that flowed to the surface lake. We learned about air currents that transported airstreams around our globe. We discovered the reality of plate tectonics and the ever-changing hydrogeological system.
