The mid-latitudes of East Asia are characterized by the interaction between the Asian summer monsoon and the westerly winds. Understanding long-term climate change in the marginal regions of the Asian monsoon is critical for understanding the millennial-scale interactions between the Asian monsoon and the westerly winds. Abrupt climate events are always associated with changes in large-scale ci...

The relative value of lacustrine resources to hunter-gatherers, while debated contentiously among Great Basin archaeologists for nearly three decades, has been largely ignored in Cali­ fornia until recent efforts by Hartzell (1992), Basgall (1993), Hddebrandt and Mikkelsen (1993), and HUdebrandt (1997 [diis volume]). In the Great Basin and arid southeastern Califor­ nia, the debate has focused ...

Abstract Reports on the presences of petrified wood fossils in Padangcermin, Lampung, are rare, no strong examination that expose scientific concern its paleoenvironment perspective. By published geological map, these was found area labelled as Cretaceous sedimentary rock (145-66 mya). Recently, known oldest fossil Indonesia, is from Miocene epoch (23.03-5.33 It an interesting circumstance to e...

Abstract Globally, lacustrine carbonate rocks are often found in rift lake basins. Because they do not form large-scale conventional or unconventional reservoirs, have received enough attention previous oil and gas exploration. Recent years, exploration examples China show that has close relationship with gas. Mudstone deposits always a good effect the area. However, genesis of is still controv...

Integrated terrestrial and marine records of northeast African vegetation are needed to provide long high resolution records of environmental variability with established links to specific terrestrial environments. In this study, we compare records of terrestrial vegetation preserved in marine sediments in the Gulf of Aden [Deep Sea Drilling Project (DSDP) Site 231] and an outcrop of lacustrine...

The Upper Cretaceous/Lower Tertiary Maghra El-Bahari Formation at Gabal Ataqa and Gabal Shabrawet in the northeastern portion of the Eastern Desert of Egypt is subdivided into two informal lithostratigraphic parts: lower and upper. The lower part has common features of alluvial floodplain-dominated deposits with occasional occurrences of crevasse splay deposits. The upper part has sediments typ...
