Comminution is the process by which mined ore is reduced in size to make for easier processing. The strict definition is 'the action of taking a material, specifically mineral ore, and reducing it to minute fragments or particles'. This is typically achieved in several stages of a detailed and professional miningoperation. Jaw C…
The Mongolia-Okhotsk Ocean was subducted locally at the end of the Late Paleozoic. The scissor closure from the west to east began in the Late Triassic. Most scholars proposed that the closure of the Mongolia-Okhotsk Ocean was during the Middle-Late Jurassic [12,13,14]. Rhyolite of the Manketou'ebo Formation belongs to A-type …

1. Introduction. Rural settlements are an important living space for the rural population [1–3].Spatial and temporal distribution patterns reveal the footprints of human-land interaction and the coupling process of changes in the human-land relationship [4, 5].Meanwhile, as the core for grasping adjustments to the rural human-land relationship, …
Focal mechanism data provide information on the relative magnitudes of the principal stresses, so that a tectonic regime can be assigned. Especially such information is useful for the study of intraplate seismic active regions. A study of earthquake focal mechanisms in the territory of Mongolia as landlocked and intraplate region was conducted. We …
Revealing the patterns and influencing mechanisms of spatial and temporal distribution of rural settlements is crucial for rural revitalization and sustainable development. However, our limited understanding of the rural settlements in China's ethnic minority border areas has hindered the process of their agricultural and rural …
There is genetic diversity of hair types in the Inner Mongolia cashmere goat population. Previous studies have found that fibroblast growth factor 21 (FGF21) and PI3K-AKT signal pathways may be related to different hair types in Inner Mongolia cashmere goats.Therefore, the purpose of this study was to explore the effects of the PI3K-AKT …
The Yaoba Oasis is an irrigated cropland entirely dependent on groundwater; previous investigations (1980–2015) revealed an over-abstraction of groundwater and deteriorating groundwater quality.
The Mongolian Plateau is in the eastern segment of the CAOB. Since the Cenozoic era, many regions have been reactivated to form the Mongolian Plateau, including the Altai, Mongolia, and Baikal rift zone (Fig. 1) (e.g., Tapponnier et al., 1982, Delvaux et al., 1997, Cunningham, 1998, Cunningham, 2001, Bayasgalan et al., 2005).Various …
The map of focal mechanisms of earthquakes in Mongolia could be useful tool for researchers in their study on Geodynamics of Central Asia, particularly of Mongolian and Baikal regions.

This tiny species is the smallest snake in Mongolia. The Brahminy Blindsnake, as its name suggests, is almost completely blind. It has small, translucent eyes that can detect light but not form images. Although native to Mongolia, this species is naturalized worldwide.
It allows the bottom of the pitman to move up and down with the motion of the eccentric shaft, apart from serving as a safety mechanism for the entire jaw. The piece of non-crushable material such as a steel loader tooth (sometimes called "tramp iron") enters the jaw crushing chamber and being larger than the closed side setting it can't be ...
Central Inner Mongolia, located at the junction of plates, has undergone multi-phase tectono-magmatic activities and boasts abundant shallow hydrothermal resources. However, there is a lack of in-depth research on deep hot dry rock (HDR) geothermal resources in this region. Based on the regional geological and tectonic settings, …
