Crystal-bearing fine ash vitric tuff of the High Island Formation, High Island Reservoir M), eastern New Territories.

The formation is compositionally homogeneous with a high-silica rhyolite chemistry. The very fine-grained matrix contains c.20% of crystals dominated by small euhedral alkali feldspars, with some larger broken fragments of quartz and feldspar. High precision U-Pb dating of single zircon crystals has yielded an age of 140.9 ± 0.2 Ma for the formation (Davis et a!., 1997).
