Andesite rock is commonly used as a heritage building in Southeast Asia, especially Indonesia. However, the study on consolidation of andesite still limited. This aimed to evaluate application effectiveness TEOS-based material type materials. TEOS was modular system with powder form mortar. andesite-TEOS mortar applied conservation techniques, for gap and joint filling. 
 successfully rock...

In the present work, the non-spherical dust grain characteristics of comet Levy 1990XX with different silicate grain compositions (both pyroxene and olivine) are studied using the T-matrix method. Considering amorphous pyroxene grain (MgxFe1−xSiO3) with x (= 0.4, 0.5, 0.6, 0.7, 0.8, 0.95, 1) and amorphous olivine grain (Mg2yFe2−2ySiO4) with y (= 0.4, 0.5) (Dorschner et al. 1995), the observed p...

Karapınar-Karacadağ Volcanic Rocks (KKVR) have very complex magmatic history and outcropped the southwestern part of Cappadocia Province (Central Anatolia). Here we present petrography whole-rock chemistry enclave-bearing rocks to constrain their source evolution history. These petrographic observation geochemical data reveal that enclaves in volcanic are magma mixing/mingling (MME), segregatio...

Magmas with matrix glass compositions ranging from basalt to dacite erupted a series of 24 fissures in the first 2 weeks 2018 Lower East Rift Zone (LERZ) eruption K?lauea Volcano. Eruption styles ranged low spattering and fountaining strombolian activity. Major element trajectories glasses melt inclusions hosted by olivine, pyroxene plagioclase are consistent variable amounts fractional crystal...

A large number of polished stone implements from Palaeolithic to Bronze Age sites of Northern Italy and Southern France are made of high-pressure (HP) metamorphic rocks (eclogite and related rocks), mainly consisting of Na-pyroxene (jadeite to omphacite) from the metamorphic belt of the Western Alps. The standard archaeometric study of prehistoric stone implements follows a procedure that is in...
