The Plagioclase series is a group of related feldspar minerals that essentially have the same formula but vary in their percentage of sodium and calcium. Albite and Anorthite are the end members of the series, with the intermediary minerals Oligoclase, Andesine, Labradorite, and Bytownite. The acclaimed Dana's System of Mineralogy lists the intermediary members as individual minerals, whereas ...

Apr 25, 2017· The Mohs Hardness Scale is the primary scale that tests a rock's hardness by how easily it can be scratched. Diamond has a score of 10 on the hardness scale, which is the highest a mineral can obtain. Talc has a score of 1, and gypsum has a score of 2, which makes these two minerals similar and difficult to differentiate between.

Selenite can look similar to calcite, but the main identifier is that selenite is very soft. Gypsum is a 2 and calcite is a 3. It's only a difference of 1 on the Mohs scale, but it's a huge difference because a fingernail has a hardness of 2.5. You can scratch selenite with your fingernail but not calcite. Calcite has a ton of unique identifiers.

Albite belongs to the Plagioclase Feldspar group, an isomorphous solid solution series.Albite is one end member, containing sodium and no calcium. The other end member, Anorthite, contains calcium and no sodium.The intermediary members are Oligoclase, Andesine, Labradorite, and Bytownite.Oligoclase and Andesine are considered by some to be a variety of Albite rather then a separate mineral.
