Hi durklis

I have made some minor edits and set a poll.

This was your original translation:
Conducted researches enabled extraction of crystalls of bismuth-containing minerals that are rarely found in nature, as well as investigation of their habitus.

I think 'habit' is the correct English name for 'habitus' where crystals are concerned; see for example
http://books.google.co.uk/books?id=CjO2_4-l8xsC&pg=PA13&lpg=PA13&dq=habitus+crystal&source=bl&ots=rPXnBidhz3&sig=4qfkTsge1ZpTWyzAE6gWmwqrnV8&hl=en&sa=X&ei=1itaT8T3M5HJ8gOFzY3cDg&redir_esc=y#v=onepage&q=habitus%20crystal&f=false

Do let me know if you do not agree with my edits

Hi, Lein.

I admit "habitus" and "habit" are false friends of translator and that mislead me I found an article in Wikipedia about crystal habits.

Performed researches enabled extraction of synthetic crystals of bismuth-containing minerals that are rarely found in nature, as well as investigation of their habits.

Hi again

I reply here to make it easier to keep track of what we are doing and to which translation we refer

This is what you said:
There is an indication to many researches in the original text… (Corresponding noun and participle are in plural form.)

In English, 'research' does not have a plural form (a bit like 'milk' doesn't).
Research can refer to one or more studies. Would you prefer 'studies' instead?

Thank you for improving my English Studies would be better in this case.

It seems interesting that "Wiktionary" approve plural form, see
http://en.wiktionary.org/wiki/researches

They do say it is rare though; and apart from that I wouldn't believe everything you find on wikipedia

Add an adjective "synthetic" before word "crystals", please.

I'd say:
enabled the extraction --> enable to obtain
rarely found --> extremely rarely found
as well as investigation of their habits --> as well as research their habits (just to match "to obtain" at the begining)

Edited: Agree with habits vs habitus, made the same mistake myself

Sorry you answered while I was editing.

Never pretended my English was perfect though

I will still insist on first 2 corrections. Impovising is great if no words were missed or their meaning hasn't changed.

Done! Thanks all
