The Ironstone Beds of Oolitic age in Lincolnshire have, during the last four years, yielded not only large quantities of brown hæmatite iron-ore, but some very interesting sections and borings, comprising thirty-one of the latter between four and seven miles to the south of Lincoln, and several extensive openings showing that the beds are much richer at this distance from Lincoln, but that they become very siliceous and pass into a ferruginous sand above Normanton about eighteen miles to the south.

1. The irregular oval line, delineated on the annexed map (Plate XIV.) shows nearly the inner edge of a limestone bason, in which all the strata of coal and iron ore (commonly called Iron Stone) in South Wales are deposited; the length of this bason is upwards of 100 miles, and the average breadth in the counties of Monmouth, Glamorgan, Carmarthen, and part of Brecon, is from 18 to 20 miles, and in Pembrokeshire only from 3 to 5 miles. 2. On the north side of a line, that may be drawn in an east and west direction, ranging nearly through the middle of this bason, all the strata rise gradually northward; and on the south side of this line they rise southward, till they come to the surface, except at the east end, which is in the vicinity of Pontipool, where they rise eastward.

The relevance of the study is to develop a methodology for monitoring manufacturing objects us-ing unmanned aerial vehicles formed as a result of mining operations. The Tashtagol iron ore deposit is located in the south of the Kemerovo region in Gornaya Shoria, and is being worked underground. The development of the reserves of the South-Eastern section has been carried out since 2004 by the Tashtagol branch of company Evrazruda. A special feature of the South-Eastern section reserves min-ing is the operation of protected objects within the zone of potential hazardous displacements, as a re-sult of which, presumably in November 2017, a sinkhole was formed in the area of Mount Boulanger. The aim of the work is to describe the method of monitoring the determination of the geometric dimensions of the sinkhole in different periods of time using an unmanned aerial vehicle. The sinkhole development has been monitored since 2018. As a result, this study determines the geometric dimensions of the sinkhole in different periods of obser-vations, and calculates the average sinkhole increase dynamics of the per year.

The metamorphism of the Durness dolomite horizons in the aureole of the Beinn an Dubhaich granite of Skye has long provided one of the best known examples of dedolomitization and progressive thermal metamorphism of siliceous dolomites recorded in the literature. Harker's study (1904) concerned itself primarily with assemblages regarded as derived without notable accession of material during metamorphism and the occurrence of products of metasomatic origin at the contact of the granite has hitherto received but little notice in print. Yet as long ago as 1897, Geikie had written of this contact: “… the most abundant and interesting deposits are metalliferous. Fragments of a kind of ‘gossan’ may be noticed all along the boundary line of the boss, and among these are pieces of magnetic iron ore and sulphides of iron and copper. The magnetite may be seen in place immediately to the south of Kilbride. A mass of this ore several feet in diameter sends strings and disseminated particles through the surrounding granophyre and is partially coated along its joints with green carbonate of copper” (Geikie, 1897, p. 384). It is of interest to note further that a record of “a mineral resembling humite” from this same contact is made in the Annual Report of the Geological Survey for 1896 (1897).

Orogenic Belts

AbstractIntensive structural and stratigraphic studies, supplemented by nine new absolute age data, have led to the recognition of two distinct orogenic belts in the Pre-Cambrian tract of Singhbhum and adjacent areas in India. The Iron Ore orogeny in the south, characterized by the generally low grade metamorphic, N.N.E.–S.S.W. trending formations, had its culmination in the emplacement of the batholithic body of Singhbhum granite (c. 2,000 m.y.). These rocks are separated by a prominent thrust zone (Copper Belt thrust) from the E.–W. striking, generally high-grade meta-morphic rocks of the Singhbhum orogeny whose closing age is 905 to 934 m.y.
