Acoustic emission and thermal infrared signals are related to the process of rock breaking. In this paper, the acoustic emission and thermal infrared signals of rock are obtained during the loading process of indoor granite freeze-thaw cycle test and uni-axial compression test. Then the acoustic emission signals sent out during rock breaking are an...

Fluid exsolution in magmas is a process that, in many silicic upper crustal reservoirs, starts at relatively low crystallinities (near liquidus), and precedes the precipitation of many ore bodies, including pegmatites. As any magmatic system approaches its solidus, the amount of the exsolved fluid phase increases and becomes progressively dominant ...

For the first time, cathodoluminescence (CL) was used to show oscillatory zoning in perthitic K‑feldspars from the equigranular Toki granite, central Japan. Based on the CL patterns, two types of zoning are identified: single core oscillatory zoning (SCOZ) and multiple core oscillatory zoning (MCOZ). The SCOZ is defined by oscillatory zoning around...

Polymer concrete is a composite material used to replace cast iron and steel in wafer grinding machines for vibration damping. During the grinding and lapping processes of manufacturing silicon wafers, excessive vibrations may cause subsurface damage which requires additional polishing and reduces yield. Nine compositions containing various levels ...

In this study, physical, chemical, structural and radiation attenuation properties of some granite samples collected from Kütahya-Simav and İzmir (Bergama and Karaburun) were investigated. The true particle density of the studied granite samples was in the range of 2.65 g cm−3 to 2.72 g cm−3 and the median particle diameter was between ∼12 μm and 4...

Hydraulic fracturing (HF) technology is crucial to form connected fracture network within the low-permeability geothermal reservoir. However, the HF process and failure mechanism in this process are only partly understood. A series of true triaxial hydraulic fracturing tests on large-scale natural granite samples were conducted under different conf...

This research investigates small-scale tectonic activity in the Jiujing region in Beishan, northwest China through the application of persistent scatterer (PS) Interferometric synthetic aperture radar (InSAR). PS InSAR is an effective monitoring tool in this unpopulated, arid, and unvegetated rural area, whose surface geology is dominated by a sing...

Poor marketing infringes the rate of production and supply of quarry end products and limits the supply rate between the producer and the industrial users. This study aimed at assessing the structure, conduct, and performance of the granite marketing system in Ogun and Ondo, recognizing and characterizing the opportunities and constraints on market...

In deep mining and high-concentration nuclear waste storage engineering, the surrounding rocks may be subjected to the combined action of high-temperature fire and impact load. In this study, the fracture morphology and the energy dissipation of granite following high-temperature treatment at 25–800°C were analyzed using the split Hopkinson pressur...
