Cleavage: Mineral Properties
If a mineral has Perfect Cleavage, One Direction; Poor Cleavage, Two Directions, this means that the mineral has perfect cleavage on two sides, and poor cleavage on the other four. In this guide, cleavage quality is measured in numbers, then the amount of sides, separated by a comma. 1 is perfect cleavage, 2 is good cleavage, and 3 is poor ...

The upper part of the bauxite layer (0–3 m) is massive and contains gibbsite, Al-goethite, hematite, and anatase. The massive pisolitic bauxite gradually transforms into a bauxitic clay with a relic parent-rock texture and large amounts of kaolinite in the lowermost 1.5 m (Fig. 5 a–d). The pisoliths have concentric layering and occasionally ...
