Thrust fault, footwall syncline, and growth strata.  View southward of (1) footwall syncline (red conglomerate at left = Miocene Tupiza Formation conglomerate, Central Tupiza basin), (2) east-vergent Palala thrust with hanging wall composed of gray Ordovician rocks (middle), and (3) growth strata (tan conglomerate at right = Miocene Oploca Formation, Western Tupiza basin).  See Fig. 5 in Horton (1998).
 

Thrust fault, footwall syncline.  Close-up view of (1) vertically dipping conglomerate (red strata at left = Miocene Tupiza Formation conglomerate, Central Tupiza basin) that becomes younger from left to right, (2) a footwall syncline (in uppermost red-orange strata), and (3) the Palala thrust (near vertical dip in this area, placing gray Ordovician rocks on Tertiary conglomerate).  View is to the south.  Road for scale.
 

Basal Tertiary unconformity. View northward of the eastern margin of the Central Tupiza basin (near Palala dry river bed, 3 km NW of town Tupiza).  The orange mudstone in the foreground is the 400-m-thick Oligo-Miocene Catati Formation, which unconformably overlies (with only slight angularity) the gray Ordovician rocks (at right) and is overlain by the Tupiza Formation conglomerate (the dark red "fins" at the left).  House at base of Catati for scale.
 

Conglomerate section. View southward of ~800-m-thick section of Tupiza Formation conglomerate, Central Tupiza basin, in the Palala dry river bed (8 km NW of town Tupiza) (Fig. 6A of Horton, 1998).  These deposits are younger from left to right (from east to west).  The Palala thrust is about 200 m to right (west) of photo edge.
 

Debris-flow conglomerate. View northward of lower Tupiza Formation conglomerate, Central Tupiza basin, in the Palala dry river bed (8 km NW of town Tupiza).  These deposits are younger from right to left (from east to west).  These matrix-supported, cobble-boulder conglomerates represent deposits of debris flows on an alluvial fan that was derived from the hanging wall of the Palala thrust a few km to the west.  For scale, the wall at right is 2 m high.

Conglomerate section. View southward of steeply dipping Tupiza Formation conglomerate, Central Tupiza basin, along the Rio San Juan del Oro (8 km S of town Tupiza). These deposits are younger from left to right (from east to west).
