“…Based upon eroded basaltic features in the Yucca Mountain area, it is expected that the most likely mechanism for magma ascent is by dikes between 0.5-4.5 m wide and a few hundred to a few thousand meters long. Table 1 indicates material properties of the representative trachybasalt (hawaiite) magma [Vaniman et al, 1982]. Volatile contents for these magmas are typically $1 -3 wt.% but can range up to 4.6 wt.% [Nicholis and Rutherford, 2004] and the effect of this is reflected in the relatively high explosivity of the Lathrop Wells volcano, the youngest ($75-80 ka) in the region [Valentine et al, 2005].…”

We investigate the interaction between Yucca Mountain repository drifts (horizontal emplacement tunnels) and a hawaiitic magma in three scenarios: (1) a single feeder dike that extends above an intersected drift; (2) same as 1 but with an additional secondary dike extending upward from the drift; (3) same as 1 with the drift initially filled with pyroclasts and gas under high pressure which is then decompressed as might happen if some blockage is rapidly removed in the volcanic system above the drift. Our results indicate that the drift is likely to experience dynamic pressure waves from expansion of rising magma and subsequent pyroclastic flows, with a maximum possible dynamic pressure of ∼107 Pa. A secondary dike above the drift has negligible effects upon the flow dynamics. In the third scenario, particles settle fairly quickly along the floor of the drift, suggesting that a swift decompression within the drift will not be able to remove all the magmatic materials.

“…Red Cone (Figure lB), located about 8 km N-NW of Lathrop Wells volcano, is an older (40Ar/39Ar ages between 0.92-1.10 Ma; Perry et al, 1998;BSC, 2004b) volcanic center of similar composition (Vaniman et al, 1982) and volume to the Lathrop Wells volcano, also with two lava flow fields, and with the remnant of a main cone that marks the vent area. Because of its age it is extensively eroded and drainage networks have developed that extend fiom lava flow margins to the upper slopes of the remnant cone.…”

“…The hawaiitic (Vaniman et al, 1982) Lathrop Wells volcano (Fig. 1A) has a total eruptive volume of about 0.09 km3 and consists principally of: (1) a -140 m high scoria cone that is being rapidly quarried, (2) two aa lava flow fields, one of which flowed south-southeastward (south lava field), and a second that flowed initially northeastward from the cone and then wrapped toward the south (northeast lava field), and (3) a scoria lapilli and ash fallout deposit that might have extended as far as 20 km north of the cone (Perry et al, 1998;BSC, 2004a).…”

“…The Lathrop Wells volcano (Figure 1) is the youngest (75-80 ka; Heizler et al, 1999) volcano in the Crater Flat Volcanic Zone, southern Nevada (see Crowe and Perry, 1989;Vaniman et al, 1982;Crowe et.al., 1982Crowe et.al., , 1983BSC 2004a). The volcano is composed of evolved alkali basalt (hawaiite, or trachybasalt;Vaniman et al.…”
