Long-form identifier:

GUID (UUID V4):

Other/historical names associated with this locality:

Hertogenwald; La Helle

Outcrop in a hydrothermally altered tonalite intrusion.

Located 7 km west of Monschau and 10 km SE of Eupen, in the valley of La Helle (Hill) stream.

Related to the Lammersdorf tonalite on the eastern side of the Belgian-German border (http://www.mindat.org/loc-235848.html).

According to Hatert et al. (2002), Dimanche & Sterpin (2001) reported finding micrometre-sized chromite and zircon grains associated with gold, rutile, and martite in iron hydroxide crusts "from the High Fens region, above the confluence of the Helle and Soor streams".
Hatert et al. (2002) re-examined the X-ray diffraction results of Van Wambeke and found out that what Van Wambeke had described as tetradymite is in fact joseite-B.

ⓘ Albite

Formula: Na(AlSi₃O₈)

Description: a major constituent of the tonalite (Schreyer & Abraham, 1978)

ⓘ Aleksite

Formula: PbBi₂Te₂S₂

Habit: lamellae

Colour: light grey

Description: Inclusions in joséite-B as lamellae of up to 70µm. The highly reflective light grey lamellae show evident anisotropy in greenish grey to yellowish-grey under the polarized reflection microscope. The identification of the mineral is also based on its chemical analysis by electronic microprobe which leads to (Pb0.76Bi0.24)Bi2.04Te1.99(S1.90Se0.07), with lower contents in Sb (0,14%), Cd, Zn (0,04%) and Fe (0,02%) as well.

ⓘ Benjaminite

Formula: Ag₃Bi₇S₁₂

Description: Highly reflective light grey grains of up to 50µm as inclusions in the tellurides. Anisotropy is fairly strong in yellowish grey tints. Identification was confirmed by chemical analysis with the electronic microprobe which leads to (Ag1.80Cu0.58Zn0.27)(Bi5.56Pb2,02)(S11.39Te0.33) with lower Fe contents (0,12%).
