ABSTRACT:

An opening review of the time series of Spanish, German and British
lead mining production is informally discussed in the context of
historical, technical and economic change, and intuitively-visual
impressions of outputs offered.
In the formal development the non-ferrous mine production of South Wales
is analysed with especial reference to the Zipfian statistical paradigm.
Three non-zipfian statistical rank provinces are identified for the
eighteen documented South Wales lead mines.

ABSTRACT:

The non-zipfian statistical rank provinces for the napierian logarithm
of lead metal production is further examined, this time for historical
Montgomeryshire and Shropshire as well as South Wales.
The cubic equation suggests itself the general model of this kind of rank
distribution, but the Coefficients of Determination of polynomial regressions
are examined in detail and the efficacy of Logically Switched and Fourier Series
data models examined.

ABSTRACT:

The subaerial cartography of the lead mines of the Shelve Plateau is revisited and
six-figure OS grid references due to Burt et al are compared with the Author's
eight-figure fixes determined with the help of archives in the Public Record Office
at Shrewsbury. A Poissonian distributional study determines that the two series of
positions broadly agree except for an anomalous class interval which is an artifact of the
difference in the two grid precisions.
When the Author's figures are plotted on maps four dramatic curving traces are seen
to follow the mines across the Earth's surface ( "Arcuate Features" ).
At the traces' two major intersections two of the three most prolific mines developed.
These arcuate features may represent mineralised ancient conchoidal fault fractures
around an intrusion at depth.
