upthrow 
of the two adjacent rock-faces, it is sometimes observed 
that the bedding of the formation has been influenced in 
its position along the line of the fault, and to a greater or 
less distance from it, the dip being downward on the 
downthrow side and upward on the upthrow side of the 
fault. This is called by the miner "dipping to the down- 
throw" and "rising to the upthrow." Also used attribu- 
tively. 
We rarely meet with a fissure which has been made a 
true fault with an upthrow and downthrow side. 
Beikie, Geol. Sketches, xi. 
upthrust (up'thrust), n. A thrust in an upward 
direction; in geol., an upheaval; an uplift. A 
term rarely used, and then generally as meaning a thrust- 
ing or lifting upward of a mass of rock niore violent in its 
motion and more local in character than is generally under- 
stood to lie the case when the term upheaval or uplift is 
used. Thus, the uplift of a continent ; the upthrust of a 
mass of eruptive or intrusive rock. Also used attribu- 
tively.

tion of the old crystalline floor, succeeds another mass of 
" spotted rock." Quart. Jam. Geol. Soc., XLVI. 218.
