The discovery of macrofossils at Selumar, Belitung, Indonesia

l('F.G. Hosking' & T.E. Yancey; Jabatan Geologi, Univ. Malaya, Kuala Lumpur H • L. Strimple, Dept. Geology, Uni v. Iowa, Iowa City,.' Iowa, USA; and M.T~ Jones, Broken Hill Prop. (Indonesia), Kelapa Kampit, Belitung,

Indonesia.

This note is. written on order to record the,first disc;very . of well preserved, in situ, macrofossils on Belitung Island, Indonesia, as well as to provide details of the circumstance~ of the discovery, the geological environment in which the fossils occu~ together with. a preliminary account of the best fossil specimen that was recovered, and the geological significance of the find. .

At Selurnar (Fig.,l) a wide essentially magnetite/cassi~erite orebody outcrops wh~ch elsewhere along' the strike was once mine4.· . for tin by tl1e Dutch" using \l,ndergrounq methods. Early in 1974, . when one o~ Us (K.H.) visited the outcrop, it was bei~g exploited by P.N.·. Timah for jig ragging. This work had exposed a nearly vertical hanging wall which, because ofa prominent parting, had developed a 'few inches inside the ore-body proper. On the broken ore, close to this wall, a well-preserved greyish-white crinoid, , partly embedded in.the black megnetite-rich ore, was found by K.H. and is described,below. Further immediate search~ but of short

. duration, revealed. a llumber of crinoid fragmen~s in the foot-wall., and on the following day a,mQre intensive se~chby two: of 'us (M.J. & K.ij.) resulted in the discovery of still more fragments there. A 'month or so later further search by M.J. and some of his colleagues recovered another good crinoid specimen ~rom the site~ but this has not yet been described. .

It is thought th~t the fossil locality at Selumar maybe rather restricted as there is no record of fossils having been foUnd in the underground mine, and.it is most unlik~ly that Dr Adam, the excellent ,geologist. who was associated with the company that operated the mine, .would· have failed to record them had they occtiI'red there.

The fossils found at Selumar are all crinoids, and include 'a well preserved cup with arms (crown), various segments of articulated crinoid stems up to 40 cm long, and many disassociated crinoid elements. They are all referable to a single species of inadunate crinoid of the genus Moscovicrinus and even the scattered columnals

Warta GeoZogi, VoZ. 1 No.2, Mac-ApriZ 1975

35

can be referred satisfactorily to the species. This crinoid has a . rather small cup with large plates, long robust arms with many plates, and many thincolurnnals with large diameter and very large inte;rnal , opening, giving the stern a resemblance to a pipe and the individual columnals a resemblance to a ring. .

The Selurnar crinoid ap~ears to be related to Moscovicrinus multi­plex (T.ra~tschold, 1867) which has been reported in the literature from tq,.e Myachkovian Formation (Hoscov~an = Desmoinesian), U.S.S.R. Th~,9~,ly ?ther sp'ecies' current1yreported for. the genus 'is M. bjPin­natus Lane $0 Webster, 1966, frqm the ~~o1fcalIllnan (Lower Permian of Nevada,' U.S.A. The Se1umar crinoids 'are·thought to be Lower Permian in age.

The pr~vious very ~entative determination of Stephanian (latest carboniferou~) age plant remains, made by Jongmans and cited by van OvereelIl~(1960) is probably PerJYlian rather than Carboniferous ... .:.and·' it is q\,lestionable if'the plant~ are preserved welienoiighto be identifiabJ.e ~t" a1J..The fusulinids round along the 'north coast of· Beliturtg C1,;r:'e.p.e;'D1ian;,and thecass:i.teri,tized,arnrnonite. (Asathiceras sp,) fromtlle sQuthernpart of the iSland is also'Permian, but was found as ,~l,oat ~~ a Quaternary placer~ , . , .

The$elu~r crin9id~are ~lso re~rkabie in'th~t' they have been rep lac ec;Lby ,: a ~ffiQer· of ,the set1>ent~rie group of minerals that is almost . cer~~dnly cl"4tigorite. In this t antigori te'thel';'e are occasional small crystals of magne~~te, generally 'rim-replaced by hematite, and equallyslll,C1,li individual crystals or aggregates of hematite. The matrix in wbich the crinoidS· are embedded· consists essentially' of .. comparativeiy'large crystals of magnetite that have been superficially altered to hematite. 'Antigorite', locally with small magnetite/ hematite an4_hematit~ inclusions, and the rare crystal of cassiterite, occur betwe~nthe large . magnetite cIystals •

.. ' I I ' , '.' .

. ,A' d:i.sc~ssion .of the possible historY of replacement of these origirtally Ga1ci'tic,organic remains, together with 'the nature and genesis of'the Selumar ore..;.body, will form the subject of a later not~.

World Campus Afloat

On 15 April 1975 the Society organized trips to the Sungai Besi Mines, Kuala Lumpur and the Jabatan Geologi, Universiti Malaya for a group of students of the Horld Campus Afloat when the~r ship called at Port Kelang. At the mines the stud~nts Here shQwn .~he geology of the area, tin mining methods and'mineraldressing 'pro­ces~es. Later, at the Jabatan Geologi they were brie-fed on the genera~<ge:6'l6gyof Malaysia artd:'also shown colieqtiops of Ma;laysian rock's";{minerals '~nd fosstls. .. . / ...

The leaders of the excursions were Encik E.B. Yeap and Encik L.C. Wong.

Students Loan Fund

Since the Fund \'1as established, many student members have obtained generous loans from the Society to help them pay for their field expenses and preparation of theses. However, tb~" money now available from the Fund is critically low as most recipients of loans have not repaid the interest-free loans as soon as possible.' 'A'fVa 'result many deserving stttde1lt;mernb~-rs this year have not been given loans to pay for their field expenses and theses preparation. As the expenses for fieldwoIl1<l,. and theses preparation have gone up considerably in the pas't--year manY'of -thel3e'::deserving"studen't n'Iembens -are fa:cing; financ:l.a).,.: difficulties.
