Question: Who coined the alternative name regarding a geological concept of the orogenic belt that was active in Gondwanaland?

Context paragraphs:
Orogeny: An orogeny is an event that leads to a large structural deformation of the Earth's lithosphere (crust and uppermost mantle) due to the interaction between tectonic plates.  An orogen or orogenic belt develops when a continental plate crumples and is pushed upwards to form one or more mountain ranges; this involves many geological processes collectively called orogenesis.

Alpide belt: The Alpide belt or Alpine-Himalayan orogenic belt is a seismic belt and orogenic belt that includes an array of mountain ranges extending along the southern margin of Eurasia, stretching from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic.  It includes the Alps, the Carpathians, the Pyrenees, the mountains of Anatolia and Iran, the Hindu Kush, and the mountains of Southeast Asia.  It is the second most seismically active region in the world, after the circum-Pacific belt (the Ring of Fire), with 17% of the world's largest earthquakes.

Robert Millner Shackleton: Robert Millner Shackleton FRS (30 December 1909 – 3 May 2001) was a British field geologist who developed an interest in the geology of East Africa.  He initiated structural studies across orogenic belts in Tanzania-Zambia-Malawi (in the late 1960s), major studies across the Limpopo Belt and adjacent Archaean greenstone belts of Zimbabwe-Botswana-South Africa (in the 1970s) and projects across the orogenic systems of Egypt, Sudan and Kenya (in the early 1980s).  Just prior to his death he was working on a detailed compilation of the Precambrian geology of East Africa.  At the age of 75 he led a Royal Society geological traverse across Tibet, in collaboration with the Academica Sinica, Beijing.

Sveconorwegian orogeny: The Sveconorwegian orogeny was an orogenic system active 1140 to 960 million years ago and currently exposed as the Sveconorwegian orogenic belt in southwestern Sweden and southern Norway.  In Norway the orogenic belt is exposed southeast of the front of the Caledonian nappe system and in nappe windows.  The Sveconorwegian orogen is commonly grouped within the Grenvillian Mesoproterozoic orogens.  Contrary to many other known orogenic belts the Sveconorwegian orogens eastern border does not have any known suture zone with ophiolites.

Tectonic evolution of the Aravalli Mountains: The Aravalli Mountain Range is a northeast-southwest trending orogenic belt that is located in the northwestern part of India and is part of the Indian Shield that was formed from a series of cratonic collisions.  The Aravalli Mountains consist of the Aravalli and Delhi fold belts, and are collectively known as the Aravalli-Delhi orogenic belt.  The span of the whole mountain range is about 700 km in length.  Unlike the much younger Himalayan section nearby, the Aravalli Mountains are much older that can be traced back to the Proterozoic Eon.  The collision between the Bundelkhand craton and the Marwar craton is believed to be the primary mechanism for the development of the mountain range.

Fold and thrust belt: A fold and thrust belt is a series of mountainous foothills adjacent to an orogenic belt, which forms due to contractional tectonics.  Fold and thrust belts commonly form in the forelands adjacent to major orogens as deformation propagates outwards.  Fold and thrust belts usually comprise both folds and thrust faults, commonly interrelated.

Geology of the Alps: The Alps form part of a Cenozoic orogenic belt of mountain chains, called the Alpide belt, that stretches through southern Europe and Asia from the Atlantic all the way to the Himalayas.  This belt of mountain chains was formed during the Alpine orogeny.  A gap in these mountain chains in central Europe separates the Alps from the Carpathians to the east.  Orogeny took place continuously and tectonic subsidence has produced the gaps in between.

Geosyncline: Geosyncline is a geological concept which was developed in the late 19th and early 20th centuries before the concept of plate tectonics was developed.  A geosyncline was described as a subsiding linear trough that was caused by the accumulation of sedimentary rock strata deposited in a basin and subsequently compressed, deformed, and uplifted into a mountain range, with attendant volcanism and plutonism.  The filling of a geosyncline with sediment is accompanied in the late stages of deposition by folding, crumpling, and faulting of the deposits.  Intrusion of crystalline igneous rock and regional uplift along the axis of the trough generally complete the history of a particular geosyncline.  It is then transformed into a belt of folded mountains.  Thick volcanic sequences, together with greywackes (sandstones rich in rock fragments with a muddy matrix), cherts, and various sediments reflecting deepwater deposition or processes, were considered "eugeosynclinal" deposits of the outer deepwater segment of geosynclines.

Samfrau Orogeny: The Samfrau Geosyncline or Samfrau Orogeny is an orogenic belt that was active in the Palaeozoic and early Mesozoic in Gondwanaland, formed by small terranes and deep accumulations of old sediment dumped off the continent's edge by erosion, acccreting against the Pacific-side coast of Gondwanaland due to subduction.  Its name (as "Samfrau Geosyncline") was coined by Alexander du Toit.  Parts of it exist now in northern Argentina, South Africa, Antarctica, and part of the east coast region of Australia, as shown in the map at this link.

Hebridean Terrane: The Hebridean Terrane is one of the terranes that form part of the Caledonian orogenic belt in northwest Scotland.  Its boundary with the neighbouring Northern Highland Terrane is formed by the Moine Thrust Belt.  The basement is formed by Archaean and Paleoproterozoic gneisses of the Lewisian complex, unconformably overlain by the Neoproterozoic Torridonian sediments, which in turn are unconformably overlain by a sequence of Cambro–Ordovician sediments.  It formed part of the Laurentian foreland during the Caledonian continental collision.
