| Description | Syenite is a plutonic igneous rock related to granite but containing only very minor amounts of quartz. This sample of syenite is typical: dominated by whitish K-feldspar. The dark mineral is hornblende. Quartz and magnetite are also present but are difficult to identify in hand specimen. This sample comes from Magnet Cove, Arkansas. The rocks of Magnet Cove are part of a 100-million-year old igneous complex containing rare and unusual rock types. Many of the rocks are alkalic and silica poor, and so contain rare and unusual minerals. Magnet Cove is a world-famous mineral collecting spot. This specimen is 10 cm across. |
