ABSTRACT Located in the southwest corner of Ratanakiri Volcanic Province, Wat Ocheng basalt is first known zeolite locality Cambodia. The a fine-grained, vesicular to amygdaloidal, subalkaline transitional alkaline intraplate tholeiite comprised 30% lath-like plagioclase (average: Ab51An45Or4), 35% interstitial augite Wo44En35Fs21), 25–30% zeolites after and volcanic glass, minor skeletal ulvös...

We present a first paragenetic study of the Wuyier, Wuyisan, Wuyiyi and Shihongtan sandstone-hosted roll-front uranium deposits, northwest China. The mineralization is hosted by Lower–Middle Jurassic coarseto medium-grained sandstones, which are dark-gray to black due to a mixture of ore minerals and carbonaceous debris. The sandstone is alluvial fan-braided river facies. Minerals associated wi...

Further mosaic-like data were recorded on the mineral occurrences of Carpathian–Pannonian region in this fifth member series arranged by countries and localities. Each “mosaic” contains a concise description, mainly based XRPD, SEM-EDX EPMA measurements description paragenesis. Some minerals are first-time descriptions from entire discussed region, but all newly documented for at least describe...
