Anisian foraminifers from the high-tatric series of the Tatra Mts

ABSTRACT: The assemblage of Anisian :foraminifers found for the first time in the hlgh-tatric serJes of the Taotra Mts includes the stratigraphieally dmporta.nt forms, GZom08piTa densa (Pantic) and GlomospiTeUa gTandis {SalaD, indicative of the datest Early Anisian through Early 1Il1yrian age. The TeOOgn.ized Animan assembl.a.ge appears manedly impoverished quantitatively and quaUtBtively ID reletion to -the oon,1lem- poraneous Tethyan assemblag-es, despite of ddezrtical microfacies development of ,the

foraminifers-bearin·g sequences.

'INTRODUCTION

The Anisian foraminifers in the high-tatric series have first been found in th€ course of mdcrofacies studies of the Middle Triassic deposits at Mt. Komdny Tylkowe in the Tatra Mt5 (cf. Fig. 1; and Belka 1976).

The profile of the Anisian deposits continues from the Iwaniacka Pass (1460 m a.s.1.) to Mt. Rz~y .on the southern slopes of Mt. Kominy Tyl.,.

kowe, attaining about 320 m in thickness (Figs 2-3). The deposits are highly differentiated iinpeti'ology; being generally poor in floral and faunal remainS.

DISTRIBUTION OF FORAMINIFERS IN THE PROFILE

Anisian foraminifers were found only in the upper part of the profile at Mt. Kominy Tylkowe. They are limited to three horizons, I, Il, and III (cf. Figs 3-4) in a series of biopelsparites, pelmicrites and ostracode bio- micrites about 130 m thick (series "E" of Piotrowski, 1965, PI. 1).

The foraminifer assemblage comprises the following taxa:

A mmodiscus incertus (od'Orbigny, 1839) - PI. 1 Fig. 7 _4mmodiscus sp. - Pl. 1, Fig. 6

Glomospira densa (pan tie, 1965) - PI. 1, Figs 15-16 Gtomospira cl. densa (Pan tic, 1965) - Pl. 1, Figs 10-11 Glomospira sp. - PI. 1, Fig. 13

Stratigraphically important species, Glomospira densa (Pantic) and Glomospi1'ella grandis (Salaj), were found in horizon 1, in a sample taken from gastropod hiopelsparites (PI. 2, Figs 4-6) that occur 195 m above the conventional lower boundary of the Anisian, situated at 1640 m a.s.l.

(cf. Figs 2-4). Some representatives of Dentalina sp. were found in

REMARKS ON FORAMINlFERS

The foraminifer assemblage comprises representatives of two fa- milies, Ammodiscidae (8 taxa) and Nodosariidae (2 taxa). The foraminifers are relatively poorly preserved, and their chamber walls are often recrystallized,the internal structure thereby being poorly visible. This is related to an advanced sparitization of originally micritic matrix, leading to a gradual "disappe'arance" of foraminifer tests in the matrix (vide PI. 2, Figs 4-6).

The Anisian foraminifer assemblage from the high-tatric series of Mt. Kominy Tylkawe appears to be markedly impoverished quantitatively and qualitatively in relation to the ~ontemporaneous assemblages known from the sub-tatric (Choe) series (cf. Gazdzicki & Zawidzka 1973) and other· parb; of the Tetbys (vide Borza 1970, Baud & a1. 1971, Premoli Silva 1971, Urosevic 1971), as well as from the epicontinental Muschelkalk

environmental conditions unfavourable for faunas and floras predominat- ing in that basin 'and resulting in an advanced "barren" character of the rugh-tatric Middle Triassic deposits of the Tatra Mts.

AN-lS1A'N FORAlM.LNJFERS FROM THE HIGH-TATBIC SERrES 433-

STRATIGRAPHY

The Ani9ian stage in 1he high-tatric series 'Was dilStinguished by Lefeld (1957, 1958) 'Who recorded the occurrence of the crinoid species DadocrinU8 grundeYi Langenhan. The lower boundary of that stage 'Was- conventionaRy drawn at the basal breccia, as the -underlying limestone and covernous dolo:mite series -was known to yield Costatoria costata (Zenker) and NaticelZa costata Winkler typical of the Upper Scythian, Le;

Ca~pilian (cf. Kotailski 1956, 1959). The upper boundary was drawn at the top of the series "E" of Piotrowski (1965) -in the profile of Mt. Kominy TylIrowe yielQing Physoporella pauciforata (Giimbel), P. -prealpina Pia, DiplopcYTa annulatissima Pia, .Macroporella sp., and Griphoporella sp.- indi- cative - according to Kotanski (in Piotrowski 1965) - of the turn of the Pelsonian and Illyrian.

Only two foraminifers of those reported from horizon I, Le. Glomo- spira -densa and Glomospirella grandis, are of a marked stratigraphic importance. Their stratigrapbic range coincides with that of ~ Glomo- spira densa Zone 1 (Range Zone: uppermost Lower Anisian, Pelsonian and Lower myrian).

Dasyc1adacean algae (cf. Fig. 4; and Piotrowsk4 1965), occurring above the foraminifer-bearing horizon I, are indicative of Pelsoruan - Eady Illyrian age (cf. Ott 1972a, b; 1974). It would follow, therefore, ~t

foraminifers of the -genus Nodosaria, reported from the foraminifer~:

-bearing horizon Ill, are generally of Illyrian age.

The range of the Glomospira den.sa Zone is markedly wider than the range of the recognized assemblage of dasycladacean algae. The forami- nifer-bearing horizon I :is situated, however, about 90 m below the place where the first dasycladacean algae were found in this section; it seems, therefore. that the association of guide foraminifer species corresponds here only to the lower part of the total range of the Glomospira densa Zone. On the other hand. the wpper part of the section that yields the dasycladacean algae may correspond to the upper part of the stratigraphic range of that aSsemblage. This seems to result from variability and succession of facies in, the Upper Anisian of the Tatra Mts (cf. Fig. 4; and- Belka 1976).

Lt may be conclUded that the isolated records of foram1nifers and_ rJgae from the Anisian of Mt. Kominy Tylkoweare insufficient for reliable draWing of the suh6tage boundaries in tl'ris section.

1 'I'he -UJP.PE!!r part CIf tibe GlomoBptra densa zon~ sensu SaiLaj (1974) was thought to cover the whole myrian (5818j 19'14). iHowever, correlations of that zone wi1lh dasyc1adacean and oCO'llOdoot zones ,(Jendrej8lrova 1973, Budurov & TToifonova 1974, GatiU£Ckd & a3.~ 1975) have shown tb1l'l; thios zone does not OOIlIIPl'ise !the UlWer myrian.

SEDIMENTARY CONDITIONS

Dasycladacean algae and foraminifers were found in biPelsparites, pelmicrites and ostracode biomicri.tes forming the upper part of Mt. Ko- miny Tylkowe section. Although the stratigraphic ranges of these fossils .overlap to a significant degree, their occurrence sites do n~t 9verlap in the section. This seems to be the result of dependenc~ i~f th~efossils on facies. The genera Glomospira and Glomospirella, were found, in bio- pelsparites with clay admix.ture (cf. PI. 2, Figs 4-6), ahd the number of individuals seems to increase along with enrichment of the rock. !in clay matter. The rocks of the foraminifer-bearing horizon I belong to that type rich in clay matter. The clay admixture is sharply reduced in pelmicrites overlying horizon I and in rthese pelmicrites dasycladacean algae appear for the first time (Fig. 4). This is in ·accordance with the widely held opinion that dasycladacean algae and especially Physoporella pa'Uciforata almost exclusively occur in limestones devoid of clay admixture (cf.

Hurka 1967, Bechstadt & Brandner 1970). Because of this clear dependence

·on facies, they cannot 'be treated as ideal guide fossils.

The microfacies studies have shown that the upper part of the.

Anisian from Mt. Kominy Tylkowe with its. sedimentary sequence and fossils reflects a marked trend· to shallowing of the sedimentary basin (cf; Bel"ka 1976). Representatives of Glomospira and Glomospirella are known from seruments deposited at about 30 m depths from other parts of the Tethys, and dasjcladacean algae reported from the upper part of the section attain the maximum development in well-oxidated waters ~t 6-10 m depths (cf. Bechstadt & Brandner 1970).

FlINAiL REMARKS

The Middle Triassic floral and faunal remains occaSionally found in the high-tatric series of the Tatra Mts are insufficient for any more detailed correlations and comparisons of this high-tatric -sedimentary basin with those of other .zones of the Tethyan geosyncline. Taking into account a wide distribution of the so-called vermicular limestones, the secfunentary sequence was compared to the contemporaneous deposits of !pe Brian-

~onna[s zone from the Western Alps (Debelrnaa 1961, Kotaflski 1964) ..

However, considering the results of analysis of foraminifer assemblages and miomfacies (Belka 1976) it may be stated that comparable Middle Triassic microfacies with similar foraminifer fauna are fairly common throughout the TethYl3. They are known, e.g., from the Dolomites (Bech- stadt & Brandner 1970), Dinariides (Paffiic 1965), Bulgaria (Trifonova &

Catalov 1975), Crimea (Voloshina 1974), Caucrasus (Efimova 1974), Iran (Bronnimann & aI. 1972) and Pakistan (Zaninetti & BrBnnirp,ann 1975).
