Palynostratigraphy of the Keuper and Rhaetic in north-western margin of the Holy Cross Mts

Here were presented results of studies on microflora found in the Keuper and Rhaetic deposits from north-western margin of the Holy Cross Mts. Studied material came from 6 boreholes: Radwan6w IG 1, Eugeni6w-Korytk6w IG 1, Mniszk6w IG 1, Studzianna IG 2, Nieswin PIG 1 and Opoczno PIG 2. Seven spore-poUen assemblages were distinguished and 94 species of microspores from 54 genera as well as 7 ' species of Acritarcha from 3 genera were recognized.

INTRODUCTION

Palynological studies of the Upper Triassic deposits from north-western margin of the Holy Cross Mts were done in 1987-1990. Samples for them were taken from boreholes: Radwan6w IG 1, Eugeni6w-Korytk6w IG 1, Mniszk6w IG 1, Studzianna IG 2, Nieswin PIG 1 and Opoczno PIG 2 (Fig. 1).

Main aim of this work was microflora characteristics, distinguishing of spore-pOl- len assemblages and analysis - first time - of palynostratigraphy of the Keuper and Rhaetic deposits from mentioned area. Relatively complete scheme of such strati- graphywas prepared (Tab. 2), correlable with palynological zones found in the Upper Triassic from north-western Poland by T. Orlowska-Zwolinska (1983, 1985).

First data about occurrence of Late Triassic miospores in the Holy Cross Mts were

presented by T. Orlowska-Zwolinska (1972, 1981, 1983). They refered to three bo-

reholes: Boza Wola IG 1, Solec 60 and Gacki 1, located in southern and south-western

part of studied region. Other informations about microplankton foundings ofAcritar-

cha group in the Lower Keuper deposits from Bukowie - NE part of the Holy Cross

GENERAL CHARACTERISTICS OF STUDIED LITHOSTRATIGRAPHICAL COMPLEXES

TIlE KEUPER LITHOSTRATIGRAPHY

The Keuper lithostratigraphy from mentioned area was elaborated by H. Jurkie- wicz (H. Jurkiewicz, 1980; H. Jurkiewicz et at, 1973a, b, 1976) and refered to similar scheme proposed by A. (1960) and 1. Gajewska (1978) for Polish Lowland. H. distinguished the Lower and Upper Keuper, the last one included: Boundary Lower Gypsum Beds, Reedy Sandstone and Upper Gypsum Beds (Tab. 1).

The Lower K e u were found in four borehole

Radwan6w IG 1 - depth m (H. Jurkiewicz, 1980; H. Jurkiewicz et at, 1976), Studzianna IG 2 - depth: 1574.0-1696.0 m (H. Jurkiewicz et at,

NieSwin PIG 1-": depth: 887.0-1042.0 m (Z. Kowalczewski ed., 1991) and ...

iJ'-''''~~ ... 'U'

PIG 2 - depth: 940.3-1059.5 m Kowalczewski ed., 1991, 1992). In their part occurred intercalations of dark siltstones, sandy siltstones and sandstones. Flora detritus was abundant there. In upper part of Lower

these deposits transformed into grey-greenish claystones with marly interbeds. In the Radwan6w IG 1 borehole some laminae and imprints of gypsum were found. The of described complex was series of claystones, 70 m thick.

The B

u n dar y Dolo mit e deposits were documented in three bo- reholes: Eugeni6w-Korytk6w 1G 1 - depth: 314.2-318.2 m but the bottom of series was not reached (Z. Kozydra, 1962), Mniszk6w IG 1 - depth: 2516.0-2619.3 m (H.

Jurkiewiczetal., 1973b) and Opoczno PIG 2-depth: ?930.6-940.3 m. They consisted of light-grey dolomites, locally contained fauna remains and intercalated with grey dolomitic or siltstones.

The Lower Gyp sum Bed s deposits were found in five boreholes:

Eugeni6w-Korytk6w IG 1 depth: ?267.0-314.2 m, Mniszk6w IG 1 depth:

2372.5-2516.0 m, Studzianna IG 2 - depth: ?1484.2-1574.0 m, Nieswin PIG 1 - depth: ?750.2--887.0 m, and Opoczno PIG 2 - depth: ?776.8-930.6 m. The bottom part of them consisted of dark-grey claystones with thin marl interbeds and of do- lomites with laminae and imprints of gypsum and In part these deposits passed into siltstones laminated with claystones or mar]s.

The R e e d y San d s ton e deposits were noticed in one borehole

Mniszk6w IG 1 at the depth: 2267.0-2372.5 m. They formed complex of

light-grey, fine sandstones. In its top occurred siltstones layer with flora remains. In

other studied boreholes -except

th~

Radwan6w IG 1 described deposits

continuously passed into the Upper Gypsum Beds series. It was difficult to define

precisely the boundary between them.

dolomitic claystones with thin dolomite interbeds, contained gypsum and anhydrite. To the top they transformed into silty deposits but sulphate content gradually decreased. In the top of the Eugeni6w-Korytk6w IG 1 profile the Cherry-red and motley claystones were noted.

THE RHAETIC LITHOSTRATIGRAPHY

. The Rhaetic lithostratigraphy from studied area was elaborated by J. Kopik (1970, 1973). The Rhaetic deposits were noticed in five boreholes: Eugeni6w-Korytk6w IG 1 - depth: 120.7-231.0 m, Mniszk6w IG 1 - depth: 1483.0-2032.4 m, Studzianna IG 2 - depth: 1081.0-1304.7 m, Nieswiii PIG 1 -depth: 380.0-585.0 m, and Opoczno PIG 2 - depth: 560.5-708.0 m. In the Eugeni6w-Korytk6w IG 1 borehole these deposits began with dark-grey, cherry-red spotted, dolomitic claystones, passing into motley claystones with single bivalve shells and fish scales. There occurred fine, several dcm thick, interbeds oflimestones. Top of complex consisted of motley claystones with fine calcareous sphaerolithes. In other boreholes the Rhaetic series were composed of grey-greenish and motley siltstones and claystones with intercalations of light-grey sandstones. In the Mniszk6w IG 1 borehole, at the depth 1694.0 m, occurred 1.5 m thick bed of intraformational conglomerate. In all studied profiles the deposits of the Zagaje Series of Lower Liassic laied on the Rhaetic rocks.

THE CHARACTERISTIC OF MICROFLORISTIC ASSEMBLAGES

Author has distinguished within Keuper and Rhaetic deposits seven microfloristic assemblages (Tab. 1, 2), basing on such criterions:

- stratigraphic ranges of described species, particulary their first occurrence;

- maximum and minimum content of miospores within spectrum;

- general taxonomic composition of spectrum;

- occurrence of microplankton from Acritarcha group.

I ASSEMBLAGE

This assemblage occurred in the Lower Keuper deposits from four boreholes:

Radwan6w IG 1 - depth: 152.5 m and 261.5-218.2 m (A. Fijalkowska, 1989; A

Fijalkowska, A Trzepierczynska, 1990), Studzianna IG 2 - depth: 1641.8-1644.6 m

(A Fijalkowska, 1988b), Nieswiii PIG 1 depth: 970.3-978.3 m (A. Fijalkowska,

1991), and Opoczno PIG 2 depth: 1030.3 m. It contained index species Heliosaccus

dimorphus Madler (PI. III, Fig. 11). The dominant element of the I assemblage was

pollen grains - 56.9% of all miospores there - among which the most frequent were

forms possessing two sacci Disaccites, 45.7% of assemblage - of genera: Succinc-

vailed taxons of genus Calamospora. Less numerous were specimens of genera;

Anapiculatisporites and Todisporites. Within subturmaAuritotriletes - 9.8% of trum -dominated specimens of genus Carnisporites: C. granulatus Schulz (PI. III, 3), C. omatus Madler (PI. III, Fig. 1) and C. cf. mesozoicus (Klaus) Madler (PI. III, Fig.

2).

V ASSEMBLAGE

The V assemblage was found in the Upper Gypsum Beds in boreholes: Eugeni6w- Korytk6w IG 1 - depth: 218.4-221.5 m (A Fijalkowska, 1989), Mniszk6w IG 1 - depth: 2086.4 m (A. Fija lkowska, 1988a),

Nie~win

PIG 1 - depth: 605.5 m (A.

Fijalkowska, 1991), and Opoczno PIG 2 - depth: 771.2-775.5 m. Its quantitative and

taxonomic composition was impoverished. There dominated pollen grains of genus

Corollina with index species C. meyeriana (Klaus) Venkatachala et G6czan (PI. V,

Fig. 1). Less numerous were specimens of genera: Ovaiipollis, Enzonalasporites and

Monosulcites which could suggest the Subzone a from lower part of C. meyeriana Zone,

distinguished by T. Orlowska-Zwolinska in the Upper Gypsum Beds. That opinion was confirmed with lithological characteristics of deposit.

VI ASSEMBLAGE

The VI assemblage was documented in the Rhaetic deposits in two boreholes:

Eugeni6w.Korytk6w IG I-depth: 195.0-196.0 m (A. Fijalkowska, 1989) and no PIG 2 - depth: 578.8 m. It contained the index species C. meyeriana

Venkatachala et G6czan. Pollen grains content was 81.2% of all

quent were specimens of genera: Pinuspollenites and Triadispora. Among Azonaletes - 3.0% of assemblage prevailed taxons of genus Corollina: ^C. meyeriana (Klaus) Venkatachala et G6czan, C. zwolinskai Lund (PI. IV, Fig. 7) and Granuloperculatipol- lis. Relatively numerous were grains of Praecolpates - 23.0% of assemblage - belonged mainly to Monosulcites.

VII ASSEMBLAGE

The VII assemblage was noticed only in one borehole Studzianna IG 2 at the depth 1108.0-1123.0 m (A. Fijalkowska,

1988b).

It

was

66.0% of spectrum from subturma Azonotriletes, to genera: Cyathidites, Concavisporites, Todisporites and Lycopodiumsporites. pollen 34.0%

of assemblage- prevailed Disaccites -18.7% - from Pinuspollenites. Plicates consisted 12.0% of all assemblage. Frequent were Monosul- cites and Cycadopites.

CONCLUSIONS

This work was

~he

first detail study of palynostratigraphy of the Upper Triassic deposits from NW of the Holy Cross Mts. on the stratigraphic ranges of miospores and their quantitative content within seven microfloristic as- semblages were distinguished within Keuper and Rhaetic series.

The I assemblage represented upper part of Helisaccus
