Extrusive igneous rocks are formed the main part of geological units in northeast region of Birjand. Investigation shows that these igneous rocks can be divided into rhyolitic, dacitic, andesitic and an especial group including basaltic andesite and basalts. In Later group that differ from the others according to geochemical and mineralogical characteristics, there are limited outcrops of high ...
Abstract Jovian Trojan asteroids make up a large group of primitive bodies that populate Jupiter's L4 and L5 Lagrange points. The Trojans’ dynamics composition carry insight into the formation mechanisms shaped our solar system. Mid-infrared (MIR; 5–35 μ m) spectra Trojans exhibit puzzling silicate emission features, like optically thin comet comae, which may be interpreted as “fluffy” regolith...
This study aims to shed light on processing pathways towards functional silicate ceramics, which show some promise in various emerging applications, including dielectrics and bioactive implant materials. Polycrystalline ceramics of Neso, Soro Inosilicate families were synthesised by three different techniques: (i) a co-precipitation method, (ii) modified sol-gel method (iii) standard solid-stat...
Laser-induced breakdown spectroscopy (LIBS), accompanied by chemometric data analysis, is used to identify and classify gemstones of various hardness. The study involves several gemstones: amethyst, aquamarine beryl, bloodstone citrine, diopside, enstatite. Their hardness determined through a correlation utilizing the spectral intensity ratio ionic atomic lines an identified element in LIB spec...
