41. Another anticline has been mapped to the north of this ring syncline , which is also concentric with it. 42. The Maracaibo syncline formed later in this stage due to " inversion of Eocene rift-related structures ". 43. The fault is associated with the Taythes Anticline to its west and the Fell End Syncline to its east. 44. It and associated strata of the Unkar and Chuar groups are preserved in a prominent syncline and fault block. 45. To the north of the monoclines the Paleogene sequence is deformed into a gentle syncline , the Bouldner Syncline. 46. To the north of the monoclines the Paleogene sequence is deformed into a gentle syncline, the Bouldner Syncline . 47. A major geological feature of the Upper Carboniferous sub-period in South Wales is the South Wales Coalfield syncline . 48. A smaller outcrop of Palaeocene and Eocene deposits occurs in a small syncline to the south-east of Salisbury. 49. This syncline is oriented east west, located on the west coast south of the mouth of the Pieman River. 50. At the lowest levels of the syncline within the Coal Measures it is heated geothermally before rising to the surface.
