Talk:Plagioclase

Potential Rename

Should we rename (with appropriate redirection) this article? I think Plagioclase feldspars is more accurate because it reflects the fact that plagioclase is really a mineral group. Jon 12:37, 12 March 2006 (UTC)

No, correct term is "plagioclase", not "plagioclase feldspar". Siim 14:45, 12 March 2006 (UTC)

Article began with word "plagioclase", now it's replaced with "In geology, plagioclase". Why so? Plagioclase is a group of minerals and therefore it's not only geological term. IMHO, articles should preferentially begin with term in bold letters. Exceptions should be made only if really needed. Siim 14:51, 12 March 2006 (UTC)

Which source says that plagioclase is more properly called plagioclase feldspar? Siim 14:57, 12 March 2006 (UTC)

The extinction angle is an optical characteristic caused by albite twinning

It says to me that extinction angle is something which is caused by albite twinning :) What about biotite, pyroxenes and so on. They don't have albite twinning but they certainly have ext. angle. Siim 15:04, 12 March 2006 (UTC)

Agree - keep name as is, plus fixed ext. angle & In geology ... bits. Vsmith 23:39, 12 March 2006 (UTC)

I remember reading a WP policy recommendation a while ago that recommends WP articles start with 'In (field of endeavour), term is ...". It's a traditional encyclopaedia thing. I'll try to find the ref. Jon 11:41, 13 March 2006 (UTC)

Mineralogy

Distinct feature of minerals shouls be mentioned. Kunwar Rabindra (talk) 14:19, 29 April 2016 (UTC)

Chart Narrow Heading Necessary?

Seems unnecessary to make a legend and place the abbreviations in the column heading when the element fits fine. You just then need to center the percentage ranges, which I don't remember how to do at this moment. You can also shorten the table by putting the image in its own column.

Plagioclase minerals and their compositions

Name	% CaAl2Si2O8	% NaAlSi3O8	Image
Anorthite	90–100	10–0
Bytownite	70–90	30–10
Labradorite	50–70	50–30
Andesine	30–50	70–50
Oligoclase	10–30	90–70
Albite	0–10	100–90
