OBJECTIVE Disordered mineral metabolism is a common complication of chronic kidney disease (CKD) and a novel risk factor for CKD progression, cardiovascular disease, and mortality.

Parting in Minerals. Parting is a property that often gets confused with cleavage. And there is good reason for that. Parting is a break along structural planes and is parallel to a possible face, just like cleavage. However, parting differs from cleavage in some important ways. It cannot be found in every specimen as is true of cleavage for most every cleavable mineral.
