A SPECIFIC GRAVITY INDEX FOR MINERATS

This work was undertaken in order to provide a practical, and as faras possible, a complete list of specific gravities of minerals. An accuratespeciflc cravity determination can usually be made quickly and thisinformation when combined with other physical properties commonlyleads to rapid mineral identification. Early complete but now outdatedspecific gravity lists are those of Miers given in his mineralogy textbook(1902), and Spencer (M,i,n. Mag.,2!, pp. 382-865,I}ZZ). A more recentlist by Hurlbut (Dana's Manuatr of M,i,neral,ogy, LgE2) is incomplete andothers are limited to rock forming minerals, Trdger (Tabel,l,en ntr-optischenBest'i,mmung d,er geste,i,nsb.ildend,en M,ineral,e, 1952) and Morey (Encycto-ped,ia of Cherni,cal, Technol,ogy, Vol. 12, 19b4).

In his mineral identification tables, smith (rd,entifi,cati,on and. qual,itatioecherai,cal, anal,ys'i,s of mineral,s, second edition, New york, 19bB) groupsminerals on the basis of specific gravity but in each of the twelve groupsthe minerals are listed in order of decreasing hardness.

The present work should not be regarded as an index of all knownminerals as the specific gravities of many minerals are unknown or knownonly approximately and are omitted from the current list.

The list, in order of increasing specific gravity, includes all mineralswithout regard to other physical properties or to chemical composition.The designation I or II after the name indicates that the mineral fallsin the classes of minerals described in Dana System of M'ineralogy Edition7, volume I (Native elements, sulphides, oxides, etc.) or II (Halides,carbonates, etc.) (L944 and 1951). Those not so designated are there-fore silicates which will appear in volume III (in preparation). Hydro-carbons have been omitted.

As a check on published values, numerous specific gravity determina-tions were made on minerals from tjre collections of the university ofBritish columbia, using t]le Berman Gravity Balance. The determinationsof most specific gravities were made on natural material but a few, madeon synthetic material, are indicated by the letter s after the value. Ina few cases the calculated value is given, indicated by the letter c afterthe value.

274 THE CANADIAN MINERALOGIST

In the case of some isomorphous series and complicated groups suchas apatite, amphiboles, pyroxenes, and clay minerals, only well-knownmembers are listed. Specific gravities for yarietal names or unnamedminerals are generally omitted.

Dana's System of M'i'neral,ogy, Vols. 1 and 2, furnished most of thedata for minerals other than silicates. El,ements of Ohti'cal, Mineral,og,Part II, by Winchell, proved useful for silicate data. Mineral namesobtained from the above were checked in the Chm,ical' Ind,ex of Mineral,sby Hey, 1950, to eliminate any possible synonyms. The Amer'i'm'nMineral'ogi,sl and the M'ineral'ogi'cal, Magazi,ne provided data on newminerals, new data on existing minerals, and discredited minerals,thus bringing the index up to September, 1957.
