Cooper & Stanley (1990):
"The E-W lead vein seen in Carrock Mine crops out at the foot of Poddy Gill [NY328328] and a small trial has been made on it.
Wulfenite was reported from here by Davidson & Thomson (1951) and later described by Braithwaite, Greenland, and Ryback (1963) on specimens collected from the dump.
Some 'wulfenite' specimens from this locality have recently proved to be stolzite, and the orange plates of either species grown on green pyromorphite are extremely attractive.
In the 1970s Poddy Gill was diverted to by-pass the new settling ponds built for Carrock mine and material from the dump was used to dam the stream's former course."

| ⓘ Bayldonite ? Formula: PbCu3(AsO4)2(OH)2 Description: Kingsbury reference. Cooper & Stanley (1990): "'traces' from the E-W lead vein (Kingsbury & Hartley, MS; Hartley, 1984)." References: |
| ⓘ Cerussite Formula: PbCO3 Description: From a dump at the foot of the gill with pyromorphite. References: |
| ⓘ Crocoite ? Formula: PbCr6+O4 Description: Kingsbury reference. Cooper & Stanley (1990): "A specimen in the Kingsbury Collection, BM(NH), with a crudely crystalline orange encrustation with green pyromorphite on a massive galena and quartz matrix was investigated during the present study. It has an associated label: 'pyromorphite with ?mimetite and ?wulfenite on galena and quartz. Shaft on east/west vein near foot of Poddy Gill, Carrock Fell... 1951' in Kingsbury's handwriting. The orange mineral was shown by XRD to be crocoite. The result is an enigma: Kingsbury was too experienced a mineralogist to have missed the obvious possibility of crocoite: in spite of the locality having been heavily collected over the years for wulfenite and pyromorphite, the authors are not aware of other crocoite specimens from here, and the occurrence requires confirmation." |
| ⓘ Galena Formula: PbS Description: From an old working on an E-W lead-zinc vein. References: |
| ⓘ Hydrocerussite ? Formula: Pb3(CO3)2(OH)2 Habit: minute pearly plates in quartz Description: Kingsbury reference. Specimens from the Kingsbury Collection (BM(NH)) from the lead vein at the foot of the gill. References: |
| ⓘ Linarite Formula: PbCu(SO4)(OH)2 References: |
| ⓘ 'Mimetite-Pyromorphite Series' |
| ⓘ Pyromorphite Formula: Pb5(PO4)3Cl Habit: minutely crystalline crusts Colour: (pale) green Description: From an old trial at the foot of the Gill. References: |
| ⓘ Quartz Formula: SiO2 |
| ⓘ Stolzite Formula: Pb(WO4) Habit: plates; pseudocubic Colour: orange-yellow Description: Cooper & Stanley (1990): "EPM analysis of several different habits of the 'wulfenite' well known from the E-W lead vein at the foot of Poddy Gill, showed considerable amounts of tungsten in all samples tested. The technique used did not, however, allow the detection of molybdenum and some specimens may be merely tungstatian wulfenite (M. Rothwell, pers. comm.). Follow-up EPM and XRD analysis at the BM(NH) on a specimen provided by N. Hubbard, bearing small orange-yellow pseudo-cubic crystals on pyromorphite-mimetite, showed the mineral in question to be almost pure stolzite. It is too early to say the proportion of stolzite to wulfenite that occurs here but a re-examination of the XRD film taken at the BM(NH) for Braithwaite et al. (1963) confirms that their specimen was wulfenite." |
| ⓘ 'Tourmaline' Formula: AD3G6 (T6O18)(BO3)3X3Z Colour: black Description: Cooper and Stanley (1990): "Bundles of black crystals in a N-S quartz vein about half-way up the gill (Hitchen, 1934; Davidson & Thomson, 1951)." |
| ⓘ Wulfenite Formula: Pb(MoO4) Habit: thick rectangular (pseudocubic) and often elongated (bar-shaped) tablets; bipyramidal; up to 2 mm in length. Colour: orange-yellow Description: From a small weathered dump at the foot of Poddy Gill. |
