970. ORDOVICIAN (LLANVIRNIAN) STROMATOPOROIDS FROM THE YOUNGWOL AREA, SOUTHERN KOREA

Abstract

The Ordovician stromatoporoid Labechiella regularis (Yabe and Sugiyama) has been recovered from the shallow ramp facies of the Yeongheung Formation (Llanvirnian) of the Ogcheon Fold Belt in southern Korea. The skeletal characteristics of this species have been altered by diagenesis. It represents the first discovery of a stromatoporoid from the southern part of the Korean peninsula. This Middle Ordovician stromatoporoid occurrence extends the geographical range of the species, previously reported from other parts of Asia.
