The mineral content of moonmilk can be hydromagnesite, dolomite, huntite, [[Calcite (Inventory)|calcite]], [[Aragonite (Inventory)|aragonite]], or a variety of other minerals. It is most commonly found near the intersection of the [[Bedrock (Inventory)/Massive|massive reef]] with either the [[Bedrock (Inventory)/Forereef|forereef]] or [[Bedrock (Inventory)/Backreef|backreef]]. Moonmilk deposits can appear anywhere and on anything including other formations. | The mineral content of moonmilk can be hydromagnesite, dolomite, huntite, [[Calcite (Inventory)|calcite]], [[Aragonite (Inventory)|aragonite]], or a variety of other minerals.

The Moonmilk field of the Hydromagnesite section should be used to record any observation of moonmilk no matter its mineral content which may be hard to determine in the field anyway.
Moonmilk is a soft, white, pasty deposit. The texture is often described as having the consistency of cottage cheese. Small particles in the deposit account for the smooth texture. It can range from liquid to a dry powder depending upon the environment. The powder form is inventoried in a different field.
