TXC-A9NJahnsite-(MnMnZn) : Mn2+Mn2+Zn2Fe3+, Libethenite : Cu2(PO4)(OH)

Herdade dos Pendões Mine, São Luís, Odemira, Beja District, Portugal

Field of View: 1.12 mm

Group of honey-brown jahnsite-(MnMnZn) aggregates with green libethenite blades.
Only one sample of Jahnsite-(MnMnZn) was found. The original sample was subdivided into 3 parts, this is one of them.

7E1-4U0Reichenbachite : Cu5(PO4)2(OH)4, Libethenite : Cu2(PO4)(OH)

Alcalainha Mine, Nossa Senhora da Tourega, Évora, Évora District, Portugal

Field of View: 2.45 mm

Group of numerous elongated reichenbachite crystals inside a quartz vug (with goethite crusts/spheres).
We can also see some clear olive green libethenite crystals.
At this locality libethenite is relatively easy to find, we cannot say the same for reichenbachite.

EDS and XRD analyzed.

4RE-0P7Pyrolusite : Mn4+O2

Cerros da Cabeça do Homem e de Malpique Mines, Aljustrel, Aljustrel, Beja District, Portugal

Field of View: 1.91 mm

Short pyrolusite crystals on quartz.
The delicate wires are composed by very thin pyrolusite and another Mn hydroxide, possibly cryptomelane (not confirmed by XRD, K also seems too low).

Pyrolusite XRD and EDS analyzed.

Herdade dos Pendões Mine, São Luís, Odemira, Beja District, Portugal

Field of View: 5.6 mm

Group of zincolibethenite crystals on quartz, associated to zn bearing libethenite (clear green).
Both XRD and EDS analyzed.

X8P-5KYRhodochrosite : MnCO3

Herdade dos Pendões Mine, São Luís, Odemira, Beja District, Portugal

Field of View: 1.32 mm

Deep brown siderite aggregate. Despite the color, EDS results showed that it is a practically pure phase (Fe+Mg+Ca < 1% Wt.).
XRD and EDS analyzed.
