Stoping of Country Rock by S-type Granite and Late Tortuous Dykes, Czech Republic

Stoping of country rock migmatites: Racov quarry in the vicinity of Telc

Stoped angular block of migmatite in S-type granite. Notice straight margins. Granite truncates leucosomes in migmatite blocks. Racov quarry in the vicinity of Telc.	Detail of previous photograph: truncating of migmatite leucosome by granite. Racov quarry in the vicinity of Telc.
Stoping of country rock migmatite into S-type granite. Notice angular blocks and straight margins. Granite truncates leucosomes in migmatite blocks. Racov quarry in the vicinity of Telc.	Detail of previous photograph: a pre-existing boudin and its quartz veined neck stoped into the granite. Racov quarry in the vicinity of Telc.

Irregular, late dykes with chilled margins. Racov quarry.

Bifurcating and irregular dyke. Outcrop plane perpendicular to dyke strike.

Detail.

Irregular, pillowed? tip of a dyke. Outcrop plane perpendicular to dyke strike.

Irregular dyke margin showing a chilled margin locally transgressed by the granite along the irregularities in the contact.

Migmatite related directly to S-type granite: Vanov quarry in the vicinity of Telc.

Agmatite resulting from the brecciation of the country rock by granite intrusion.

Agmatite.

Angular blocks of migmatite inside granite.	Block of layered migmatite intruded by granite and thrusted along the granite dyke.
Disruption of migmatite by granite all the way down to cm clots of coarse biotite.	Dyke of felsic granite with several small inclusions/xenoliths of Bt-rich migmatite country rock and biotite clots. Notice concentration of blocks and clots towards the centre of the dyke, Bagnold effect. VANOV quarry in the vicinity of Telc.

Different magmas interacting in migmatite disaggregation. Vanov quarry

Dyke of Bt-rich granite intruding a migmatite with large patches of clean leucosome, showing two magmas migrating through the area during disaggregation of a partially molten migmatite.	Bt-rich irregular patches within a leucogranite: two different magmas mingling or a heterogeneous magma formed as a result of disaggregation of migmatites.
Dendritic cordierite on the left, now mostly biotite intergrown with quartz, inside a leucocratic patch in Biotite granite (see Fig. 4a in Barbey, 2007, CMP, for a similar texture). On the right, an irregular patch of Bt-rich granite: two different magmas mingling or a heterogeneous magma formed as a result of disaggregation of migmatites?
