Amy Lombari, …

Location

• (get map of valley from wiki)• Talk about pangaea ripping, africa,

Basic rift model

• Pangaea broke apart about 200 million years ago.

• Connecticut valley was affected by what processes?

• Diagrams and descriptions

sediments

• What sort of sediments are in the valley?• Why?• (stratigraphic section diagram)

• Basalt is one of the layers…

volcanism

• Basalt is found in the rift valley because of volcanism…

• Explain using the rift model, aka magma rising to the surface at the center of the rift valley

• What type of volcanism? ie: explosive v passive, how volatile, how silicious, rhyolitic lava flows or andesitic…

continued

• Lava flows into lakes = pillow basalts (include picture from behind target, or other picture)
