ABSTRACT Rattlesnake Mountain is a Laramide uplift cored by Archean gneiss that formed by offset along two reverse faults with opposing dips, the result being an asymmetric anticline with a drape fold of Cambrian–Cretaceous sediments. Rattlesnake Mountain was uplifted ca. 57 Ma and was a structural buttress that impeded motion of upper-plate blocks of the catastrophic Heart Mountain slide (49.19 Ma). North of Pat O’Hara Mountain anticline, Rattlesnake Mountain anticline has a central graben that formed ca. 52 Ma (U-Pb age on vein calcite in normal faults) into which O- and C-depleted fluids propagated upward with hydrocarbons. The graben is defined by down-dropped Triassic Chugwater shales atop the anticline that facilitated motion of Heart Mountain slide blocks of Paleozoic limestones dolomite (i.e., the Ordovician Bighorn Dolomite and Mississippian Madison Limestone) onto, and over, Rattlesnake Mountain into the Bighorn Basin. Heart Mountain fault gouge was also injected downward into the bounding Rattlesnake Mountain graben normal faults (U-Pb age ca. 48.8 ± 5 Ma), based on O and C isotopes; there is no anisotropy of magnetic susceptibility fabric present. Calcite veins parallel to graben normal faults precipitated from meteoric waters (recorded by O and C isotopes) heated by the uplifting Rattlesnake Mountain anticline and crystallized at 57 °C (fluid inclusions) in the presence of oil. Calcite twinning strain results from graben injectites and calcite veins are different; we also documented a random layer-parallel shortening strain pattern for the Heart Mountain slide blocks in the ramp region ( n = 4; west) and on the land surface ( n = 5; atop Rattlesnake Mountain). We observed an absence of any twinning strain overprint (low negative expected values) in the allochthonous upper-plate blocks and in autochthonous carbonates directly below the Heart Mountain slide surface, again indicating rapid motion including horizontal rotation about vertical axes of the upper-plate Heart Mountain slide blocks during the Eocene.

Photographs of Heart Mountain slide block basal layer and clastic dikes. a, Thin section of the basal layer at White Mountain cut normal to the detachment surface. Darker top half is the basal layer and the lower half is the Bighorn Dolomite. The lower plate is undeformed at any observable scale, as evidenced by the undeformed fossils in the Bighorn Dolomite. Calcite veins cut both the basal layer and the Bighorn Dolomite. The small crevice in the Bighorn Dolomite is filled with basal-layer material. b, Tool marks from within the basal layer at the Squaw Creek sampling area. The basal layer is only a few centimeters thick at this location. Discovered by E. C. Beutner (Malone et al. 1999). c, Cross-section of cement clinker by Yuko et al. (2000). Dark grains are belite and lighter-colored grains are alite. The concentric amalgamation of grains is typical of clinkers produced in a rotating kiln at temperatures sufficient to allow sintering to occur. d, Armored grain from the basal layer at White Mountain. In the center of the armored grain is a volcanic clast. Surrounding the clast are concentric layers of material that are identical to the matrix material, differing only in having a finer grain size. The majority of center grains are calcite, followed in percentage by volcanic grains and all occasionally the center for nucleation of armored grains. Although less common, some concentric armoring forms around adhered masses of matrix material as seen in figure 4e. e, Clastic dike in the upper-plate Absaroka Group Volcanics at Silvergate, Montana. f, Carbonized wood found in clastic dikes at the Silvergate sampling site. The wood is not interpreted to be reworked, as it is entirely enclosed by matrix material (see Pierce 1979; sample was collected by W. G. Pierce and is from the W. G.

Schematic representation of the relationship between the timing of intrusive events and the emplacement of the Heart Mountain slide (not to scale). Prior to slide emplacement, the diorite stock intruded host Madison and Bighorn Formations at ∼49.8 Ma. Just before emplacement of the Heart Mountain slide, a younger pluton intruded at ∼48.9 Ma. As the slide was emplaced, both intrusions were sheared off. The diorite was fully crystallized, and the second intrusion was not. The second intrusion was at least partially molten, and this molten material (now volcanic glass and other igneous minerals, such as zircon, olivine, magnetite, etc.) was incorporated into the basal layer during emplacement. The basal was injected as dikes and sills during emplacement.

Schematic sequence of events at White Mountain (modified from Malone et al. 2014a; not to scale). Before the initiation of the Heart Mountain slide, a diorite stock intruded a succession of Paleozoic carbonate and Eocene volcanic rocks at ∼49.9 Ma. The emplacement of a lamprophyre intrusion at ∼49.19 Ma caused failure and collapse of the upper plate. This slab was catastrophically emplaced to the south and east into the adjacent Bighorn and Absaroka Basins. The basal layer carbonate ultracataclasite (CUC) contains cataclastic carbonate material derived from the upper plate, euhedral and abraded zircons from the lamprophyre and other intrusions, and delicate volcanic glass.
