Opis
(Description):
galerija mineralov je elektronski indeks mineraloške baze podatkov. Vsebuje več
navskrižnih indeksov. Indekse mineralov pregledujemo po imenih
(seznam mineralov v abecednem zaporedju), po razredih (glede na kemijsko
sestavo: elementi, oksidi, karbonati, fosfati, silikati, sulfidi…), po
lokaciji (tipične lokacije za številne redke minerale, z njihovimi opisi). Zbirke, z opisi
lastnosti in slikami mineralov, nepretrgano rastejo. Opisi vsebujejo mineraloške podatke,
ki jih je mogoče iskati, kemijske formule, fizikalne lastnosti in povezave
na sorodne skupine mineralov. Slike v formatu GIF (velikosti približno 10K), so
navadno vezane na večje slike JPEG (velikosti približno 50K). Izobraževalni
strežnik odpira vrata tudi v galerijo draguljev. Strežnik omogoča iskanje s
klučnimi besedami po celotnem besedilu. Dobrodošli učitellji, predavatelji,
študenti in ljubitelji mineralov! [Zapis:

Description
(Opis): Amethyst Galleries' Mineral Gallery describes over 600 mineral species (and varieties) and more than 5000
specimens (see the new specimens last updated 09-Feb-2009, and What's New last updated 03-Feb-2009), together
with several ways of accessing these descriptions. The descriptions include searchable mineralogical data, plus other
information of interest to students and rock hounds. This site displays thousands of images of previously sold mineral
specimens as a service to rockhounds, students and educators (not merely minerals currently for sale).
This server was the first rock shop on the Internet, going live (with a numeric IP) in the fall of 1994, and under the domain galleries.com in the
spring of 1995. Amethyst Galleries'Mineral Gallery
MINERALS: by name; a list of minerals in alphabetical order; by class; elements,
oxides, carbonates, etc.; interesting groupings (gemstones, birthstones, etc.);
physical properties; keys to identifying minerals; rocks; the home of minerals;
suggested books on minerals & gems; full text search; mineral identification by keyword searching.

Opis
(Description):
tabela vsebine: seznami mineralov so urejeni abecedno in
sistematično (v skladu s klasifikacijskim sistemom). Sistematična urejenost
mineralov: elementi, sulfidi, halogenidi, oksidi, karbonati, sulfati, fosfati,
silikati, organski minerali. Informacije o mineralih vključujejo: imena,
kemijske formule, slike in opise. Tekoče ažurirana baza podatkov omogoča
iskanje imen mineralov (Boolovo iskanje elementov v formulah). Povezave na:
slike mineralov, geologijo, bibliografske zapise in okrajšave. Pod povezavo
“Earth Sciences Resources” je seznam strežnikov, ki pokrivajo: geologijo,
geofiziko, kemijo, kristalografijo, mineralogijo (baze podatkov, lokacije
mineralov), muzeje, petrologijo, periodiko, programje, univerze in inštitute,
vulkane. Glej tudi: Department

Description
(Opis): Table of Contents: How to use this mineral database MINERAL LISTS:
Alphabetical list of minerals with formula and system.
Minerals, with formula and system, ordered according to Strunz classification
(1982). Other list: names of varieties, synonyms, foreign names, etc. listed
alphabetically. MINERAL SEARCH: Search database for mineral names. Bolean search database for given elements in formula.

(Description):
strukturiranje mineralov: oksidi, hidroksidi, karbonati, sulfati, fosfati,
silikati, halogenidi in sulfidi. Na voljo so strukturni podatki o mineralih.
Minerali so slikovno prikazani. Dostopna je definicija minerala, spoznamo
lastnosti in klasifikacijo mineralov. [Zapis: 25.01.2001][Ažuriranje:

Description
(Opis); The minerals are structured as: 1. Single oxides. 2. Multiple. 3. Hydroxides.
4. Carbonates. 5. Sulfates. 6. Phosphates. 7. Orthosilicates (Nesosilictaes). 8. Sorosilicates and Cyclosilicates.
9. Chain Siiicates (Inosilicates). 10. Sheet Silicates (Phyllosilicates). 11. Framework Silicates (Tektosilicates).
12. High Pressure Silicates. 13. Halides. 14. Sulfides. This site has been developed and is supported by National Science Foundation.

Hardness of a Mineral
Tip
vira / Resource type: trdotna lestvica / hardness scale
Opis
(Description):
z merjenjem trdote minerala identificiramo neznan mineral. Trdota je merilo za
odpornost minerala na abrazijo in odraža atomsko strukturo minerala. Trdoto mineralov merimo po Mohsovi trdotni lestvici, ki opredeljuje številčno
trdoto standardnih mineralov, od 1 (lojevec) do 10 (diamant). Vas zanima kako
preskusimo trdoto minerala? Obiščite strežnik! [Zapis: 25.01.2001][Ažuriranje:

Description
(Opis): The hardenss of a mineral is one of the most diagnostic and easy tests to perform in the attempt to
indentify an unknown mineral. Hardenss is a measure of a mineral's resistance to abrasion and reflects the
atomic structure of a mineral. Mohs Hardness Scale: Hardness is measured on the Mohs Scale, identified numerically hardness of by standard minerals, from 1
(softest- talk) to 10 (hardest - diamond): A mineral of a given hardenss will scratch a mineral of a lower number. With a systematic approach, you
can use minerals of known hardness to determine the relative hardness of any other mineral.
