I. Introduction. The association of teschenite and ultrabasic rocks (picrite and peridotite) in a single rock-body has now been established for several occurrences in the lowlands of Scotland. The Barnton occurrence, near Edinburgh, has been described by Sir Archibald Geikie,1 by Mr. J. Henderson & Mr. J. G. Goodchild, and by Mr. H. W. Monckton. At Blackburn, near Bathgate, occurs a picrite, which has been described by the first-named writer as a lava, but has recently been shown to be…

1. Introduction. The Carboniferous rocks at Saltcoats, Ayrshire, are intruded in the vicinity of the harbour by a complex of sills and dykes. Of the sills, the two largest are composite intrusions
XIV. The Igneous Geology of Central Ayrshire
Introduction. During the past few years the Geological Survey has been engaged in a revision of the post-Silurian geology of Central Ayrshire. While most of the area to be described was revised by
The Distribution of Trace Elements in a Scottish Permo-Carboniferous Teschenite and its Lugaritic Differentiate
INTRODUCTION In a recent description of a composite teschenite-picrite sill at Saltcoats in Ayrshire (Patterson, 1945), mention was made of a potash-rich variety of lugarite which occurs as a
Petrology and geochemistry of differentiated teschenite intrusions from the Hunter Valley, New South Wales, Australia
In the upper Hunter Valley of New South Wales a high level teschenitic sill complex emplaced into Permian coal measures derives from parent magmas which were themselves crystal fractionation products
The age of the Lugar sill and a discussion of the Late‐Carboniferous/Early‐Permian sill complex of S.W. Scotland
The incremental heating 40Ar/39Ar method has been used to date a kaersutite separate from the main theralite-picrite unit of the Lugar sill. Ar-release spectra show discordance mainly due to the
The crystallization of the teschenite from the Lugar Sill, Ayrshire
SUMMARY Twelve stages in the crystallization of the teschenite are defined by the commencement or cessation of crystallization of particular minerals. Ocellar structures, outlined by tangentially

Petrological Abstracts and Reviews
The usual method of boiling porous and schistose rock fragments in Canada balsam is not efficient. Here is described an apparatus by means of which the pore spaces in the rock may be filled with
Classification and Age of the Analcite-bearing Igneous Rocks of Scotland
The Midland Valley region of Scotland contains the world's largest known development of igneous rocks carrying primary analcite. These rocks have been described in several publications during the

Abstract Large cognate xenoliths showing rhythmic banding in anorthosite and pyroxenite are described from a camptonite dyke. Analyses of the camptonite, a pleochroic titanaugite and a titaniferous
