Discovery of a shallow oilfield in Triassic rocks in a fenland area west of Formby, as described by Lees and Taitt (1946, pp. 307–11), led to an attempt to determine the nature of the local Carboniferous rocks, which were regarded as the most likely primary source of the oil found in the Trias.

In this paper the writer deals with certain mineralogical and textural features found in the Moine and Sub-Moine Series of western Scotland, viz. garnet-zoisite calc-silicate ribs, non-garnetiferous epidotic calcsilicate ribs, sutured (crenulate) quartz-mosaic, foliation oblique to folded bedding, and the presence of abundant yellow epidote and of spots of haematite. The garnet-zoisite calc-silicate ribs have been claimed by Dr. Richey and Professor Kennedy as diagnostic of parts of the Moine Series. For the non-garnetiferous epidotic calc-silicate ribs, which have not previously been described, the name “calc-silicate ribs of Arnipol type” is suggested. These ribs occur in adjacent groups of rocks that have been mapped with the Lower Striped Schists and the Lower Psammitic Group of the Moine and with the outermost psammitic zone of the Sub-Moine.

During the Easter Field Meeting of the Sedgwick Club, portions of the Neptunian dyke at Hazier Hill, near Church Stretton, were collected and brought back to Cambridge for further examination. The material consisted of a buff-coloured, sandy mudstone with scatters of facetted pebbles of quartzite and igneous material, including weathered rhyolite, up to a centimetre in diameter. The material proved to be richly fossiliferous and the following fauna was obtained which, we believe, throws some light on the age of these sand-filled fissures :—

In the past there have been two main lines of approach to the glacial problems of East Anglia:—

(1) Attempts to find out the number of. glacial and interglacial deposits; and

(2) The direction or directions of ice-movement as shown by the constituent materials.

A fresh investigation of the boulder clays has been undertaken, combining as far as possible these two points of view, with special attention (so far) to the varieties of “Chalky Boulder Clay” (see Baden-Powell, 1948, pp. 287–8).

It should by now be fairly well realized that the West Indian islands are not a subsiding mountain range, but represent rather an Alpine or Pyrenean area in process of emerging from the sea. In the West Indies we witness something of the condition of metamorphism of the rocks as they came up. Comparison of the metasomatism of the formations in the two widely separated areas of the Alps and Antilles may provide some evidence as to how the processes operated and what sort of forces raised them up.

The Kalahari Sand formation extends over a large part of the territory of Southern Rhodesia, and it has been estimated that it covers 12 per cent of the surface of the Colony.
