Acid base accounting--An improved method of interpreting overburden chemistry to predict the quality of coal-mine drainage Acid base accounting--An improved method of interpreting overburden chemistry to predict the quality of coal-mine drainage
Acidic mine drainage (AMD), which results from the accelerated oxidation of pyrite (FeS2 ) in mined coal and overburden, has contaminated thousands of miles of streams in the Appalachian region of the United States. Acid‐base accounting (ABA), which simplifies the complex hydrogeochemical system through use of a limited number of variables, commonly is used to predict the post‐mining...

Correlation of pre-Carboniferous carbonate successions of northern Alaska Correlation of pre-Carboniferous carbonate successions of northern Alaska
Fault-bounded successions of pre-Carboniferous (meta)carbonate rocks occur throughout northern Alaska. Successions studied in detail are those in the York Mountains (Seward Peninsula), the western and eastern Baird Mountains (western Brooks Range), the Snowden Mountain area (central Brooks Range), and the Sublik and Sadlerochit Mountains (eastern Brooks range); they are correlated on the...

Deep-water facies of the Lisburne Group, west-central Brooks Range, Alaska Deep-water facies of the Lisburne Group, west-central Brooks Range, Alaska
Deep-water lithofacies of the Lisburne Group (chiefly Carboniferous) occur in thurst sheets in the western part of the foreland fold-and-thrust belt of the Brooks Range and represent at least three discrete units. The Kuna Formation (Brooks Range allochthon) consists mostly of spiculitic mudstone and lesser shale; subordinate carbonate layers are chiefly diagenetic dolomite. The Akmalik...

Numerical modelling of uplift and subsidence adjacent to the Transantarctic Mount front Numerical modelling of uplift and subsidence adjacent to the Transantarctic Mount front
The Transantarctic Mountains form one of the largest rift shoulder uplifts in the world. Uplift of the mountains, and coeval subsidence in the Ross Embayment, are modelled with both elastic flexure equations and with the viscoelastic finite element method. Most of the geological constraints are adequately satisfied by the elastic flexure equations. Uplife of the Transantarctic Mountains...
