Korshunovskoye is a skarn deposit close to Zhelenogorsk (About 250km east of
Bratsk). Korshunovskoye is part of the Angara-Ilim iron ore region. The deposit
sits in sediments of Upper Cambrian and Ordovician age. These sedimentary rocks
are cut by explosion pipes consisting of gabbrodolerites, dolerites and dolerite
porphyrites. These pipes altered the sediments at the contact zone, especially
where the sediment consisted of limestone or marble, resulting in an ore bearing
skarn.

Malobystrynskoye is a marble quarry south of Irkutsk and about 30km west of Slud'yanka. The quarry is mostly famous for it's lazurite, but the systematic collectors will also know it as type locality for Tounkite and Bystrite.

Slyudyanka is a town on the southcoast of lake Baikal. Today it is well known
for it's white marble, but as the name already reveals it was known for mica
before. From the late 17th century until the mid 20th century phologopite was
mined here. Geologically Slyudyanka consists of precambrean metamorphic rocks,
later metasomatically altered by granite intrusions. In each of the stages
interesting mineralogy was formed. Marble with spinel and Lavrovite,
metasomatites with skarn like minerals such as skapolite and phlogopite and
pegmatites with chromphyllite

Some sources even include the lazurite localities of Malobystrynskoye and Tultui
river also to Slyudyanka. On the mineral market most specimen from these
different localities are just labeled 'Slyudyanka'. A little more research is
needed.....
