AN1-LWDKintoreite : PbFe3(PO4)(PO3OH)(OH)6

Pinhal do Souto Mine, Tragos, Chãs de Tavares, Mangualde, Viseu District, Portugal

Field of View: 1.4 mm

Deep brown kintoreite crystals associated to amorphous material - a mixture od Fe hydroxides and Fe/Al phosphate (possibly due to P enriched supergene fluids interaction with goethite).
EDS and XRD characterized.

H7Y-7X5Torbernite : Cu(UO2)2(PO4)2·12H2O

Pinhal do Souto Mine, Tragos, Chãs de Tavares, Mangualde, Viseu District, Portugal

Field of View: 1.4 mm

Bipyramidal torbernite crystals.
We can see some very thin layers (slightly opaque, with a knitted texture pattern) which may already be metatorbernite.

Field of View: 2.21 mm

Metatorbernite with 'gemmy' some layers of torbernite and honey orange parsonsite crystals.

RAH-7G7Pyromorphite : Pb5(PO4)3Cl, Parsonsite : Pb2(UO2)(PO4)2·0-2H2O

Pinhal do Souto Mine, Tragos, Chãs de Tavares, Mangualde, Viseu District, Portugal

Field of View: 2.28 mm

Honey color parsonsite crystals and white elongated pyromorphite.

This is one of the rare cases, at Pinhal do Souto Mine, when the pyromorphite is not coated (partially or completely) by plumbogummite.

PU4-METParsonsite : Pb2(UO2)(PO4)2·0-2H2O, Pyromorphite : Pb5(PO4)3Cl

Pinhal do Souto Mine, Tragos, Chãs de Tavares, Mangualde, Viseu District, Portugal

Field of View: 0.84 mm

Honey color parsonsite crystals and white elongated pyromorphite.

This is one of the rare cases, at Pinhal do Souto Mine, when the pyromorphite is not coated (partially or completely) by plumbogummite.

Pinhal do Souto Mine, Tragos, Chãs de Tavares, Mangualde, Viseu District, Portugal

Field of View: 2.45 mm

Prismatic pyromorphite 'encapsulated' by white plumbogummite.
Also in the picture yellow parsonsite and 'melted' torbernite.

H27-KFLParsonsite : Pb2(UO2)(PO4)2·0-2H2O

Pinhal do Souto Mine, Tragos, Chãs de Tavares, Mangualde, Viseu District, Portugal

Field of View: 2.8 mm

Two generations of parsonsite (numerous tiny parsonsite crystals masking the former parsonsite of 'regular' size).
As a curiosity, the second generation parsonsite has shown some Al (by EDS).

4R6-K0DParsonsite : Pb2(UO2)(PO4)2·0-2H2O, Plumbogummite : PbAl3(PO4)(PO3OH)(OH)6, Pyromorphite : Pb5(PO4)3Cl, Quartz (Var: Smoky Quartz) : SiO2

Pinhal do Souto Mine, Tragos, Chãs de Tavares, Mangualde, Viseu District, Portugal

Field of View: 2.8 mm

Pyromorphite encapsulated by plumbogummite partially substituting former parsonsite (unusual short elongation for the species).

The substitution tends to be completed, but in rare cases some parsonsite relicts were found (also revealed by PXRD).

In the top right of the picture we can still see the parsonsite 'sandwiched' by the pyromorphite/plumbogummite.

Tiny yellow parsonsite of a second generation are also present in the photo.

All EDS and XRD analyzed.
