Robert Maurer's page
Bob Maurer graduated as a mining metallurgist in South Africa and worked in gold uranium and diamond mines before studying electro-chemistry at the University of London. This took him into research projects on the growth of single crystals of Alpha –Uranium crystals and the hydrogen embrittlement of high tensile steels, and to a career in engineering. After a number of jobs related to fluid flow measurement he set up Maurer Instruments Ltd where he developed a range special purpose Turbine flow meters and a range of Crude Oil Sampling equipment in addition to meter calibration systems. Bob has delivered a large number of papers on Flow Measurement, Meter Proving and Crude Oil Sampling in the UK, Europe and the USA. His main hobbies are now related to mineral and fossil collecting. It was this hobby that took Bob to the Bolivian Andes and led him on to look at the forces associated with Tectonic Movements.

Bob has given talks to HHGS and other geology groups on several topics of interest to him:
- An engineers approach to the forces responsible for tectonic and orogenic movements (December 2019)
- Our Heritage - Stone Tools and Rock Art
- Did climatic changes in Europe give rise to the rock carvings in North Africa?
- Mining for Rare Minerals in Mexico

Simplified summary of Bob's publication: Rotating Earth and Plate Tectonics

1 The most important aspect of my work was the realisation that the Planets must have an offset ‘centre of mass’(COM) in order that the mutual gravitational pull of the Sun will cause it to rotate. It is this action that gives rise to the N-S or principal axis of rotation. It is not possible to rotate a body directly from the dimensionless centre line. An offset torque force is required.

2 The offset COM will cause the Sun driven planet to ‘wobble’ as it rotates. This is noted by the Milankovitch Cycles associated with the inclined N-S axis

3 This in turn allows a force vector diagram (Fig 17B) to be drawn with an offset COM called the ‘Radius of Eccentricity’. ( E ) . This diagram shows the heavier side to be in tension (Rift Valley Africa) and the 180 degree away position to be in Compression (Pacific Basin) . FIG 20 shows this pictorially. The equation F=Mrω2Eπ/4 shows the differential circumferential tensile forces in the Earth’s outer rim

4 The above- mentioned forces will break up supercontinents by shedding crustal masses either side of the ‘heavier anchor’ mass. In Pangea, the Anchor is the African plate. The South American plate was moved westwards and the Indian and Australian plates eastwards. Laurentia also split eastwards and westwards

5 As the plates break away the mantle will be cracked (Fig 29) and magma will intrude without any force onto the Ocean floor. The ‘Sea floor spreading’ concept by Hess is replaced with ‘Sea floor stretching’ and convection currents have been consigned to a passive role in tectonic processes .
