Triassic foraminifers from the Mala!] Peninsula

ABSTRACT: The Middle to Upper Triassic foraminifer assemblages were found for the first time in Malaysia. Fifty two foraminifer taxa (including the new species Endothyra malayensis Gazdzicki, sp. n.) are' recognized in the Kodiang Limestone Formation. The asseniblages include stratigraphically important forms:

Glomospira densa (Pantic), -Glomospirella grandis (Salaj), Meandrospira pusilZa (Ho), M. dinarica Kochansky~Devide & Pantic, Earlandia gracilis (Pan tic), Earlandinita soussii Salaj,Agathammina? irilnica Zaninetti & al. and some re- presentatives of the family Involutinidae Btitschli. The studied foraminifer assem- blages-are alm.ost identical to those of the contemporaneous deposits. of various

sections of the . Tethys Realm.

INTRODUCTION

This is

1lhe

first study of Tri.a&sic foraminifers

from

the Malay Pen!insula. Their presence was previously stated

ID

the Kod'iang Lime- stone Formation

in

Kedah, North-West Malaysia by de

Coo &

Smit

(1975).

The Kodiang Limestone Formation

¹

crops out

in.

seven isolated mogotes amidSt Quaternary S'ediments (Text-figs 1 . and

2A), and

was

formally described

as

a new lithostratigraphic unit

iln

the - Malay Peninsula

^byd~ Coo &

Smit

(1975).

The

TriasSic

age of the Formation based

on

conodonts was proposed by Ishii

^&

Nogami

(1966),

Nogami

(1968)

and Koike '

(1973;

see alSo Tamura

&

a!.

1975).

1 The name "Kodiang limestone" was first informally used by Jones & a1.

(1966); -a short description of the "Kodiang limestones" was provided ' by Burton (11973).

. The

type

locality of the Fornmtioo is situated 2.5 kilomete<rs south of the village Kodiang, and 30 kilometers north of the

town

Alor Star.

The srtlr'atotype of the FOIrmation was determined

in

the mogo1Jes Bukit Keci:1 (1) and Bllk'it Ka[ong (Text-figs 1,

3A

and 4). Other exposw-es of the Kodlang Limesrfx:me Formation Illl'e

in

the mogotes Bt. Kepelu, Bt. Mu'long, Bt. Kecil (2), Bt. Kod:iang and Bt. Hantu (cf. Text-figs 1,

2AB

and

3B).

'I'he foraminJifers were studied prirna·rily in some 120 thin seotions. Almost all the described forms come from light grey, graded liniestone bedS (unit

10)

from Bt. Keeil (1) a:nd Bt. Kalong (Text-fig. 4), and from loose rodk samples whkh most probably al'so belong

to

these

The material described

in

this paper is housed

in

the Institute of Geology and Mineralogy of

~

UnliverSlity of Leiden(eoll. O. E. Smit).

HoZotype: the specimen presented in PI. 8, Fig. 1 (thin section B)"{A-12).

Type horizon: upper part of the unit 10 in Bt. Kalong, Ladinian?

Type locatity: Bt., Kalong in Kedah (North-West MalaYl3ia).

Derivation of the name: matayenris - from MalaYl3ia.

Diagnosis: Test medium-sized, of an oval outline in the equatorial section. 'Proloculus large and spherical. The final whorl incomplete, planispiral; composed of three chambers that display a tendency to uncoiling.

Material: Five specimens.

ABsociation: DipZotremina sp., Endotl1yra sataj!, Endothyra sp., Glomospira sp., TolllPtim- mina gregaria, Variostoma sp.; and Textularia sp.

Description. - The test medium in size' (as for this genus),consisting o~

spherical and large initial' chamber, and an incomplete planispiral, whorl. The final whorl evolute in equatorial section (PI. 8, Figs 1---<3); composed of three chambers increasing gradually in size. Septa thick, short and slightly inclined

in 'the direction of coiling. The single-layered wall' thick and dark, ,finely

microgranular.

Dimensions of the test (in microns): maximum diameter - ' 250-330, dia- meter of the proloculuB - c 60, thickness of the wall - tzI5-"-OO. '

Remarks. - The new species Endothyra maZayensis Gaf.dzicki, Sip. D.

differs from the hitherto known species oftheendothyras by its slightly elongated test (in equatorial section), reduced number, equaUing three, of chambers in the last whorl, and by a distinct tendency to uncoilthis whorl. This tendency, causes that the species, although assigned to the genus; Endothyra Phillips, is very close to the genus E,nd.othyraneZZa Galloway & Ha.rlton. Some 'analogies, to this new species are dislayed by the form determined as Endothyra sp. by j endre- jakova (in Kochanova, ,Mello & Siblik 1975, PI. 11; Fig. 6) ,from the Wetter!ltein Limestones (Ladinian) ,at the 'locality' SlliOka' (Slovak;, Karst, West' Carpa thiaps,

Czechoslovakia).

Occurrence. - Known from the type locality only (sample BKA-12 fr()m the upper part of unit ,10, in Bt. ,Kalong;, see Text-fig. 4).

STRATIGRAPHY

The

analysis

of the sUiCClE!SSiionof foraminifer assemblages in

""

the KodiangLimestone Formation indicates that the unit 10 of Bt.

"

Kalong (see

Tex~fig.

4) represents the time interval ranging

from

the Lower Anisian through alt lEast thel Ladinian.

The base of unit 10 (sample No. 1 - see Text-fig. 4) is dharacte-

,

rizedby the common occurrence of Meandrospira pusiUa (Ho), the pre-

sence ^of

^wthich

(PI. 4, Fig. 9), but the laok: of Glomospira densa (Pantic), Glomospirella grandis (Sawj) and" Meandrospira dinarica Kochansky- -Dev.ide &Pantic

The position of the sampling place in the

"

sequence

"

(cf. " Text-fig. 4), just beneath tihe first occurrenJCe of Glomospirella grandis (Salaj) suggests however Lower Anisian age for this interval. This very age is confirmed (cf.

I'IepOIl'ted

from the upper

part

of the section of Bt. Kalong (cf. Nogami 1968, see also Tamura

&.

a1. 1975).

The discussed conodont faunas indicate an Early or Middle Anisian age in

the

loweT part of Bt. Kalong, and a Late

Ladinlfun

or Early Carnian in Bt. Ked! and in the upper part of Bt. Kalong (see Tamura

&

a1. 1975). As the same age resulm from the foraminifer zonation, it

may be suggested that the focaminifers aiI"e not less important than the oonodonts

in recognition of the

Triaooic stratigraphy.

In loose' samples, mostly from Bt. Keeil

(1),

whliJch lithologically correspond

to

unit

10,

important is '!he presence of such forms as Involutina communis (Kristan) - PI. 9, Fig. 1; I.

~

PI. 9, Figs 2----3

,

and 5; and

.

?Triasina sp. - PI. 9, Fig. 9. All theSe, forms suggest an Upper Triassic, presumably CaTnlian-Norian age (cf. Zaninretti

^&

Bronni- mann 1974, Bronndmann

&

a1. 1975, ZalJlli,nettil 1976), and this is the first approa'ch to

the

Carruan':'NolI'ian datirig of the upper part of fue Kodia,ng Limestone Forma1;fion .. Theforamillifers from unlit 12 of Bt. Kalong (see Text-fig. 4), represented mostly by Nodosariidae, do not contain any forms

dliagnostic

of the age of their parent deposits.

age

·for'

the

' topmost par1

of the investigated sequence.

The foraminifars are often aSsociatedhy div€l'8ealgae, ', the most

common of

w'hklh

are sudh forms as: MacroporeHa alpina' Pia, 1912 - PI. 2, Fig. 5; Oligoporella sp. ---.;, PI. 2, Fig. 6; Ac;icularia sp.; Girvanella sp.; Solenopora sp.; Globochaete alpina Lombard, 1945 - PI. 2, Figs

7-8;

Clypeina besiciPantic, 1965; Tubiphites obscurus Maslov,1956 - PI. 2, Figs 2-3; and by scarce miroproblematics LadineZla porata Ott, :I968;' EaccanelZa floriformis PaIlltic, 1971 - PI. 2, Fig. 4; and Probolo- cuspis espahkensis Brormimann

&

al.,' 1974 - PI. 2, Fig. 1. Many of these taxa,

if

not displaying their stratigraphic ranges admost identlical with t'luit of the foraminifers, are at least typi'cal of the oontemporaneous deposits from various areas of the Tethys Realm (cf.

, Bystricky 1964;

Pantic

' 1965, ' 1971; Fliigel 1972; Jablonsky 1973; Bronndmann &

a1.

1974; Ott 1974;

Borza

1975; Kochanova

&

a1. 1975; Mello 1975).

The Anisian-Ladinian foraminifer assemblages of the Kodiang Limestone Formation bear close analogies to the other oontempo!I"aneous a$€mblagesof 1fb.eTethys Realm.

This is

i!ndicated both by

the

taxo- nomic oompositloo of the assemblages, by the seqUence of particular assemblages, and by the microfacies of the deposits, both developed in the neighboring regions in Burma (cf. Gramann

&

aI. 1972), Pakistan (cf. Zani!rretti

&

Bronndmann 1975), and Iran (cf. Bronnimann

&

a1.

(1974), as well as in the Caucasus (Efimova 1974) and in various regions of Europe (cf. Salaj

&

a1. 196'7; Premoli Silva 1971; Za, mnetti

&

aI.

1972; Pa:nJ1D.c 1972, 1974; Jenc:irejakova

,1973; Gazdzicki &

Zawidzka 1973; Bronndmann

& Cs.'talOlV

1975; see also

ZanJin:et1!i

1976). Moreover, the investigated assemblages are also related to those from the epioonti- nental Muschelkalk sequence

of

SQuthe!I"n Poland (cf. Glazek . & a1.

1973,

Gaz~cki &

a1. 1975).

The

Carman-Norian involitindd assemblage with Involutina commu- nis; I. gaschei, I. sinuosa sinuosa, I.sinuosa cf. pragsoides, and ?Triasina sp., which 'has been recognized in loose samples

from

Bt.Kecil

. (1) .

and Bt. Kaloitg

is

evidently related

to

the assemblages lmown from the base of the Namyan Group

of

Burma (cf. BronndmalIlD

&

al. 1975), the Nayband Formation· of Iran (cf. Zamnetti

&

Broooiimann 1974), and from some localiiies in Europe

(cf.
