Urban gravel pit lake ecosystems are particularly susceptible to flooding and anthropogenic nutrient loading, and are therefore likely to be significantly affected by the future projections of precipitation extremes. Six shallow ex-gravel pit lakes a

The Ririwai granitic ring complex has suffered a sequence of post-crystallization alteration and mineralizing processes including albitization and, close to the Ririwai Sn–Zn lode, microclinization, greisenization, and quartz-cassiterite-sulphide v

At Ririwai, Nigeria, a biotite granite has suffered extensive post-magmatic metasomatism to produce albitized, microclinized, and greisenized rocks; the latter two lithologies form the wallrocks adjacent to tin-zinc vein-style mineralization. All the

Zircon in the Ririwai biotite granite, and its albitized and greisenized varieties, is described by reflected-light and backscattered-electron (BSE) microscopy, and electron-microprobe analysis. The three rock-types show different features in their z

The mineralogy of a fault-related uranium occurrence, in clastic rocks overlying granite, is described from borehole material. Coffinite is the only important uranium mineral. Other notable minerals are sulphides, fluorite, calcite and hydrocarbon. C
