Alkali feldspar with barium (Ba) is often present in alkaline, potassic, ultrapotassic, lamprophyre and alkaline silicic volcanic rocks (refs 1–3, and references therein). It provides valuable information regarding the behaviour of Ba during crystallization of magma and its characterization. Here we report the occurrence of Ba-rich alkali feldspar (hyalophane) rim around plagioclase from basanite (Kumari Dungar, Figure 1) intrusive into the Mesozoic Bhuj sandstone in the central part of the Kachchh, northwestern Deccan Traps (NWDT), Gujarat, India.References
