the study area is situated in the middle part of the tabas block. it contains outcrops of rocks that formed along longitudinal faults in early cimmerian orogenic phase. the basin subsided along these faults from the late triassic to early cretaceous, which include two sedimentary cycles. a sedimentary cycle, related to upper triassic to bajocian is known as shemshak group. another sedimentary c...

Analysis of deformational histories along polyphase reactivated faults commonly is based on the dating of cross-cutting relationships using relative ages of offset strata or geochronological ages of syntectonically grown minerals within fault planes. However, ten Veen and Postma (1999) and ten Veen and Kleinspehn (2000) introduced a new approach to reconstructing the vertical component of synse...

This paper demonstrates how to explore a design of a multimedia supported four dimensional (4D) information system to aid geographically-oriented the documentation of the two Ottoman fortresses of “Seddülbahir” and “Kumkale” through internet. This paper also presents a methodology for the integration of historical architectonic and Spatial Information (SI) technology, and new perspectives for h...

Abstract In “The Role of Historical Science in Methodological Actualism,” Meghan Page makes a number important points about the sciences geohistory. Yet force her arguments is blunted by decision to explicate concepts like “actualism” and “uniformitarianism” as abstract methodological commitments. this discussion note, I illustrate difficulties that arise from decision, suggest way avoiding the...

By investigating genealogical relationships, we estimated the phylogenetic history and biogeography in the megophryid genus Leptobrachium (sensu lato, including Vibrissaphora) from southern China, Indochina, Thailand and the Sundaland. The genealogical relationships among the 30 named and unnamed taxa were estimated using 2009 bp of sequences from the mitochondrial DNA genes 12S rRNA, tRNA(val)...
