Exploring Geochemical Signatures in Production Water
Produced water denotes the water co-produced during hydrocarbon exploration and includes flow-back water, gas condensates, basinal brine, and/or mixtures. The hydrostatic pressure of coal bed formation water traps the gas generated in coal and shale beds.

Laoyingqing Zinc Deposit in Northeastern Yunnan
The Laoyingqing zinc deposit is located in the Pb-Zn deposit concentration district in northeastern Yunnan, with a geotectonic location on the southwestern edge of the Yangtze block. This deposit occurs in the interlayer fracture zone of the Huangcaoling Formation slate in the Middle Proterozoic Kunyang Group.

Characteristic Features of Skouries and Other Porphyry-Cu-Au+Pd±Pt Deposits
Many giant porphyry Cu-Au, Cu-Mo, and Mo-W deposits extend from the Pacific Rim to the Mediterranean and Carpathian system in Europe, the Himalayas, China, and Malaysia. However, only certain porphyry Cu-Au deposits, associated mostly with alkaline-type intrusions, are characterized by significant Pd and Pt contents, particularly in high-grade bornite–chalcopyrite and/or flotation concentrates. Such porphyry deposits include those in British Columbia, Colorado, in the Santo Tomas II deposit, the Philippines, the Skouries porphyry deposit, Greece, Elatsite, Bulgaria, the Kalmakyr deposit, Uzbekistan, the Grasberg deposit, Indonesia, Ok Tedi, Papua New Guinea, the Mamut deposit, Malaysia, and the Bajo de la Alumbrera, Argentina.

Hypoxia Environment Training Protocols
The relevant oxygen concentrations, exposure protocols, and training periods should be considered to determine training prescriptions for different sports. In the hypoxia high-intensity interval training protocol, there is an increase in physiological changes to cardiorespiratory function, power output, hemodynamic function, and performance efficacy. However, improvements in these parameters do not always produce effective results, as they depend on the training duration and the athlete’s proficiency.

Methanogenesis
Coal bed methane (CBM) extraction has astounding effects on the global energy budget. Since the earliest discoveries of CBM, this natural gas form has witnessed ever-increasing demands from the core sectors of the economy. CBM is an unconventional source of energy occurring naturally within coal beds. The multiphase CBM generation during coal evolution commences with microbial diagenesis of the sedimentary organic matter during peatification, followed by early to mature thermogenic kerogen decomposition and post-coalification occurrences. Indeed, the origin of the CBM and, moreover, its economically valuable retention within coal seams is a function of various parameters. Several noticeable knowledge gaps include the controls of coal make-up and its physicochemical position on the CBM generation and genetic link through fossil molecular and stable isotopic integration with the parent coal during its evolution.

Peralkaline Granitic Rocks
The Lower Jurassic (ca. 177 Ma) Bokan Mountain granitic complex, located on southern Prince of Wales Island, southernmost Alaska hosts a high-grade uranium-thorium deposit with past production. The complex is a circular body (~3 km in diameter) which intruded Paleozoic granitoids as well as metasedimentary and metavolcanic rocks of the Alexander Terrane of the North American Cordillera.

Rare Earth Elements
The use of analytical techniques is important and critical in all areas related to REE (Rare Earth Elements), such as basic fundamental research, exploration, mining, extraction, and metallurgical activities at different stages by different industries. At every stage of these activities, rock, ore, minerals, and other related materials have to be analyzed for their REE contents in terms of elemental, isotopic, and mineralogical concentrations using different analytical techniques.

Geological Background of Tectonically Deformed Coal in Huaibei
Tectonically deformed coal (TDC) is a type of coal in which the primary structure of the coal body has undergone different degrees of embrittlement, fracture or ductile deformation, superimposed damage under the action of one or more periods of tectonic stresses, and even internal chemical composition and structure changes.
