Rickettsiae are in many places of the world emerging or reemerging pathogens. The spotted fevers group (SFG) composes a large group of tick- and mite-borne zoonotic infections that are caused by closely related rickettsiae. The SFG rickettsiae of Southeast Asia are yet to be identified. Earlier reports have documented the endemicity of rickettsioses among adults in the Himalayan belt but no con...
Orogenic growth, characterized by formation and forward propagation of fold-thrust belts foreland basins, is predicted wedge models thrust systems. The growth the Nanpanjiang belt basin system Indosinian orogenic in southwestern South China remains poorly understood. development underappreciated due to few constraints on structural styles, kinematics ages. Surface cross sections, seismic profil...
The main tectonic features in our study region are indicated in Fig. S1. We use 190 earthquakes for the iterative structure inversion (Fig. S2a). Most of the earthquakes are shallow (< 30 km), occurred from 1996 to 2011 (Fig. S3), and are evenly distributed along the North Atlantic Ridge and the Mediterranean-Himalayan belt. Initial source parameters (e.g., centroid time, location, etc.) are co...
The Western Qinling orogenic belt (WQOB) is one of the most important prospective gold districts in China, with widely distributed Indosinian intermediate–acidic intrusions. Liziyuan Au deposit a representative northern WQOB, hosting several sections spatially associated igneous rocks. hosted by meta-sedimentary volcanic rocks Cambrian–Ordovician Group and Tianzishan monzogranite. Two periods, ...
The Minas-Bahia orogeny juxtaposed Archean crustal fragments and Paleoproterozoic magmatic arcs to form the São Francisco-Congo Paleocontinent by Rhyacian (ca. 2.05 Ga). Unravelling Minas segment of Orogenic Belt (MBO) is an important key understanding role in construction Columbia Supercontinent. Orosirian 1.9 Ga) final amalgamation was preceded a complex history accretion nuclei Proterozoic a...
Abstract Morlet wavelet analysis is a method of studying the periodic spectrum non-stationary physical signals and applied to Himalayan Tectonic Belt explore whether there any seismic periodicity, possibility harmony or commonality properties among activities different zones. The earthquake sequence during 1951–2016 with magnitudes M ≥ 6.0 analysed. Wavelet non-periodicity for Centre zone sugge...
Two hundred km of 2D seismic survey was carried out at the Lesser Himalayan Thrust Belts in Dailekh district, western Nepal. The main motivation is to elucidate geologic relationship between known oil and gas seeps, subsurface structure, stratigraphy area. This a challenging task which from its extreme structural geological complexity such as thrust faulting, tight folding, steep dip layers, st...
The Himalayan system is the result of a continental collision that occurred approximately 55 million years ago between Indian and Asian tectonic plates1,2. resulted in underthrust crust beneath Asia, deformed crustal wedge3,4. plate records complex pre-Himalayan geological history includes several basement faults reach depths 70 kilometres are oriented at high angle to front5. These bound topog...
The East Kunlun Orogenic Belt is considered as one of the important gold mineralization regions in Tethys tectonic domain. These orogenic deposits are related to intermediate-acid intrusions formed at end Paleo-Tethys evolution, but petrogenesis controversial. This paper presents a new study on geochemistry zircon U-Pb, O, S, and Pb isotopic compositions Asiha quartz diorite, granite porphyry, ...
