On April 26, 1996, Public Law 104-134 was Chart 1 .-Payment volume, by type of disbursement, fiscal year 1997 enacted, requiring all Federal payments except tax refunds be issued electronically by January 2, 1999, thus beginning a new era in electronic N Federal tax 10.5% funds transfer (EFT). This legislation, the Debt Collection Improvement Act of 1996-part of the Omnibus Consolidated Resciss...

Several Cyprus-type volcanogenic massive sulphide (VMS) deposits occur in the Jurassic ophiolitic series of the Northern Apennines. Stratabound, stratiform and stockwork deposits were formed in the western limb of the Neotethys (Ligurian Ocean) and are observed today in basalt, gabbro and serpentinised peridotite host rocks. The studied stockwork deposit at Boccassuolo occurs in basalt and basa...

Magmatic and stratigraphic settings exert a first order control on the formation of various mineral deposit types. Some sating are rich in mineral wealth while others are barren. Stratigraphic setting is of particular importance where stratif&m or stratabound minerill deposits are concerned x orebodies are commonly restricted to specific stratigraphic intervals. For example. within the area bou...

The Svärdsjö Zn-Pb-Cu deposit is situated in the heavily mineralised Bergslagen lithotectonic unit of Fennoscandian shield, south-central Sweden. Intense hydrothermal alteration followed by a strong overprint deformation and metamorphism during Svecokarelian orogeny complicate interpretation local geology. Integration whole-rock lithogeochemical petrographic methods has allowed mainly dacitic v...

Structurally controlled dolomitization typically involves the interaction of high-pressure (P), high-temperature (T) fluids with surrounding host rock. Such reactions are often accompanied by cementation and recrystallization, resulting hydrothermal dolomite (HTD) bodies including several ‘diagnostic’ rock textures. Zebra textures, associated boxwork textures breccias, widely considered to refl...

Purcell Mountains as a roadless tract of recreational wilderness area. It is located in the rugged mountain range between Kootenay Lake and the Columbia Valley, centred approximately 30 kilometres north of Kimberly (Figure 1-3-1) and is adjoined on the south by St. Mary's Alpine Provincial Park. Resource development, including mineral exploration and mining, was prohibited and any existing clai...
