Hydrothermal breccia pipe structures: general features and genetic criteria - II Phreatic breccia

Orthomagmatic origin for the Ilkwang Cu–W breccia-pipe deposit, southeastern Kyongsang Basin, South Korea

Four distinct types of fluid inclusion are associated with brecciation, alteration and mineralization in the Ilkwang Cu–W breccia-pipe deposit in the southeastern Kyongsang Basin, South Korea. The earliest fluid inclusions in igneous quartz have salinities of 35–49 wt% NaCl equiv. and homogenize by halite dissolution. This fluid exsolved directly from the melt. A CO2-bearing fluid (2–4 wt% NaCl...

Petrography and Mineralogy of Dhofar 1428 Lunar Highland Regolith Breccia

Introduction: Dhofar 1428 is a lunar feldspathic breccia found in 2006. Bunch et al. [1] briefly described mineral chemistry of Dhofar 1428. Korotev and Zeigler [2] analyzed its bulk FeO and Sm compositions. Here, we report such detailed data for Dhofar 1428. Results and Discussion: Dhofar 1428 has a distinct breccia texture with numerous fragments of rock, mineral, and glass all welded by a gl...
