I have to ask, why have you cited a paper from 1902? Did you check to make sure no new information has come along -- in natural or social science -- that might invalidate the findings in a paper from over 100 years ago? Quite a lot has been discovered between then and now.
Absolutely. Pyrometamophism dispelled John Wesley Judd's
1902 Stonehenge Bluestones "Glacial Transport" Theory.

In 1961, UK Nursery Preschoolers noticed Stonehenge Bluestones tops and bottoms
Pyrometamorphic, altered by Late Carboniferous (Pennsylvanian) Period, Namurian
Age, anthracite (metamorphic Coal Measures Formation rock) coal burnings (above
1200 °C) from inside Ancient Pembrokeshire Coalfield carbon Cave dwellings; and
Namurian, Silesian, Carboniferous, Wales - Earthwise
In 1961, UK Nursery Preschoolers noticed Stonehenge Bluestones tops and bottoms
Pyrometamorphic, altered by Late Carboniferous (Pennsylvanian) Period, Westphalian
Age, bituminous (metamorphic Coal Measures Formation rock) coal burnings (above
1000 °C) from inside Ancient South Wales Coalfield carbon Cave dwellings; and
Coal of the Westphalian, Carboniferous, Wales - Earthwise
In 1961, UK Nursery Preschoolers noticed Stonehenge Bluestones tops and bottoms
Pyrometamorphic, altered by Late Carboniferous (Pennsylvanian) Period, Stephanian
Age, sub-bituminous (metamorphic Coal Measures Formation rock) coal burnings
(above 800 °C) from inside Ancient *Bristol* Coalfield carbon Cave dwellings.
Upper Carboniferous (Westphalian and Stephanian) and its classification, Bristol and Gloucester region - Earthwise
UK Stonehenge Bluestones Pyrometamorphic Coal Caves Shoring Pillars tops and
bottoms contain a variety of high-temperature minerals, several with diverse, unusual
compositons, UK Nursery Preschoolers said. Optical microscopy, X-ray diffraction,
X-ray fluorescence, and microprobe analyses were performed by them to study their
mineralogy. A wide spectrum of rare minerals was found in Stonehenge Bluestones
Pyrometamorphic Coal Cave Shoring Pillars tops and bottoms they said.

In 1961, UK Nursery Preschoolers suggested the mineralogy of Pyrometamorphic
rocks is mainly governed by bulk chemical composition, annealing temperature,
and oxygen fugacity. Moreover, varying degrees of disequilibrium melting, mixing,
crystallization, volatilization and a variety of reaction mechanisms influence the
formation, structure and chemistry of the constituent minerals, said Allah the
UK Nursery Preschoolers, in 1961 kindergartens interviewed.
