The type of lava least likely to form a pyroclastic flow is **basaltic**.
Basaltic lava is typically low in viscosity and tends to flow easily, which reduces the likelihood of explosive eruptions that can produce pyroclastic flows. In contrast, andesitic and rhyolitic lavas are more viscous, often leading to explosive eruptions that can generate pyroclastic flows.
