The Nam Pat Group of the Nam Pat Basin, Uttaradit Province, Thailand is situated in the Nan Suture Zone. Two contrasting tectonic framework models of the Nan Suture have previously been proposed: as a main Paleo-Tethyan suture and as a remnant of a closed back-arc basin. The goal of this study is to analyze the tectonic framework of the Nan Suture and reevaluate the existing tectonic models. Th...
Oil-gas reservoir exploration using hyperspectral remote sensing, which based on the theory of hydrocarbon microseepage information and fine spectral response of target, is a new direction for the application of remote sensing technology. In this paper, Qaidam Basin and Liaodong Bay in China were selected as the study areas. Based on the hydrocarbon microseepage theory, the analysis of crude oi...
Relationships between distribution of periphytic diatoms and environmental variables in 19 rivers of the Lake Ladoga basin (Northwestern Russia) were examined using gradient analysis. On the basis of geology and river water chemistry, the Lake Ladoga basin could be separated into twomain parts, the northern and the southern sub-basin. The rivers in the northern sub-basin are slightly acidic and...
garra rufa , a bottom dwelling freshwater fish and native to the middle east, is distributed in the southwestern of iran and the tigris basin. considering the importance of length-weight relationships data of a species in different habitats, the length-weight relationship of g. rufa from 13 rivers in the persian gulf and the tigris basins was explored. the value of exponent b ranged from 2.74 t...
Introduction: One of the most prominent features of Mars is the global south to north slope of ~0.036° [1] discovered by analysis of data from the Mars Orbiter Laser Altimeter (MOLA) aboard Mars Global Surveyor. In contrast, Isidis Planitia, the floor of Isidis basin, slopes southwest at an angle of ~0.02° [2]. It has been suggested [3] that deflection of the lithosphere under a load located in...
We study inhomogeneous host-pathogen dynamics to model the global amphibian population extinction in a lake basin system. The lake basin system is modeled as quenched disorder. In this model we show that once the pathogen arrives at the lake basin it spreads from one lake to another, eventually spreading to the entire lake basin system in a wave like pattern. The extinction time has been found ...
Continental moisture recycling is a crucial process of the South American climate system. In particular, evapotranspiration from the Amazon basin contributes substantially to precipitation regionally as well as over other remote regions such as the La Plata basin. Here we present an indepth analysis of South American moisture recycling mechanisms. In particular, we quantify the importance of ca...
several riversides in order to investigate the actual status of C. sinensis infection among reverside inhabitants. The survey results showed an overall infection rate of 21.5%: An infection rate of 40.2% in the Nakdong River basin ranked first, 30.8% in the Yeongsan River basin second, 17.3% in the Seomjin River basin third, 15.9% in the Tamjin River basin fourth, 15.7% in the South Han River b...
The investigation of geo hydrological features of drainage basin is necessary for planning and implementation of various watershed development programmes. The visual interpretation techniques coupled with morphometric analysis is used in the present study to evaluate the geomorphic process of upper watershed of river Subarnarekha in the state of Jharkhand, India. Various spatial information is ...
Sedimentologic, paleogeographic, stratigraphic, structural and tectonic studies in a paleo/mesoproterozoic metasedimentary succession (Espinhaço Megasequence, southeastern Brazil) indicates deposition in a rift-sag basin. Four basin evolution stages are recognized (prerift, rift, transitional and flexural). The four stages can be represented by six unconformity-bounded tectonosequences. The unc...
