INT&ODUCTION

The authors studied the Hmestones locally intercalating Mrid-Trias- sic dolomites of the Choc nappe, exposed along western slopes of the Cho- cholowska Valley in the western part of the Tatra Mts(cf. Fig. 1). The stratigraphic and tectonic setting of these limestones was hitherto uncer- tain (cf. Zawidzka 1970, 1971, 1972). The rich foraminifer assemblages recently fourid therein ,enabled the authors to define more precisely stra- tigraphic position of the limestones, which may be of remarkable impor- tance for explanation of highly complex tectonic structure of this area.

ANISlA!N FORAMIN1IFEBS FROM WlELK:IE KORYCrSiKA

The limestones from the Wielkie Koryciska (3 in Fig. 1) occur as small tectonic slices scattered along the overthrust of the Koryciska unit of the Choc nappe ^(a in Fig. 1). Lithological features and macro- and mi- crofaunal characteristics of these limestones are similar to those of the Partnach Beds. The Wielkie Koryciska limest()nes are represented by biocalcirudites and biocalcarenites (PI. 2, Figs 1-2) with marly shale in-

tercalatioIli!;: (cf. Zawidzka 1972). Except for foraminifers, no stratigrap- hically important microfaunas (e;g. conodonts) were found, whereas fish teeth and scales are quite common. Abundance of plant detritus IS typi~

cal, particularly for those parts of rocks in which the contribution of other bioclasts decreases. Frondicularia woodwardi (PI. 1, Figs 8-9 and PI. 2, Fig. 2) is a rock~building' element of the limestones and some marly shales. Besides the latter species, the foraminifer assemblage comprises (cf. PI. 1, Figs. 1-15):

The representatives of the species Triasina hantkeni Majzon (cf. PI.

a, .

dzicki 1970, 1974). Some limestone blocks from Siwianskie Turnie, hither- to considered to be of Rhaetian age, actually represent an inversed suc- cession of the Carnian, N orian and presumably Lower Rhaetian. This is evidenced (cf. Jendrejakova 1970) by numerous Triasina hantkeni dc- curring at the base .of these limestone blocks, and Ammodiscidae, Dusto- minidae and Endothyridae recorded in their upper parts (PI. 4, Fig. 5a-b).

COMP·ARAT1lV'E REM.ABKS

The foraminifer assemblage from Wielkie Koryciska closely resem- bles those recorded indifferent regions of the Alpine';"'Carpathian geosyn- cline, viz. in the Dinarides and eastern Asia (Ho 1959; Pantic 1967, 1970;

Salaj & al. 1967; Dimitrijevic ^& al. 1968; Salaj 1969'a, b; Koehn-Zaninetti 1969; PremoliSilva 1971; Urosevic 1971; Baud & al. 1971; Zaninetti & al.

1972; Scholz 1972). These assemblages are characteristic of Upper Anisian (Illyrlan) age, and are recorded for the first time in the Polish Tatra Mts.

The foramin'ifer associations 'Of the Rhaetian of Siwianskie Turnie and Male Koryciska are characterized by the predominance of large benthic . foraminifers of th~falnily Involutinidae Biitschli which are of remarkable importance for the Upper Triassic stratigraphy in the Alpine-Carpathian geosyncline and south-western Asia (Hagn 1955; Le~

The Rhaetianof the Choc nappe from the Polish Tatra Mts most closely resembles that of the Krizna nappe (Guzik 1959, Gazdzicki 1974), developed in mixed, Swabilm-Carpathian facies (Goetel1917). Compari- sons of the Siwiaitskie Turnie and Male· Koryciska sections With more complete profiles of the Krizna Rhaetian in the Tatra Mts (Pale!nica Lendacka, Siroke sedlo, Javorina, Maly Kopieniec, Mala Swinica, Dolina Lejowa) show that the former primarily represent the Upper Rhaetian (zone with· Triasina hantkeni) whereas the facial development in· both nappic zones is the same (cf. Goetel 1917; Cepek 1970; Gazdzicki 1970, 1971, 1974). The ·Choc Rhaetian from Hybe (Kossen facies) in Slovakia does not correspond to any of Krizna Rhaetian facies from the Tatra Mts (Goetel 1917, Koutek 1927, Mahel & Kochanova 1962, Bystricky & Biely 1966, Kochanova 1967). At Hybe, the Upper Rhaetian (zone with Triasina hantkeni) is missing, and only the Lower Rhaetian with" Angulodiscus"

pokornyi and GlomospireZZa friedZi (cf. Salaj 1969a, b, Salaj & Stranik 1970, Gazdzidtii 1974) is well evidenced.
