Proposed mechanisms for sill emplacement may be tested by forms of intrusion displayed by Tasmanian dolerites. These intrusions suggest upward, fracture‐controlled, magma passage with local bedding control from an array of feeding centres whose location was determined by basement structures and regional stresses associated with the basin intruded. Many published misconceptions about these intrusions can be resolved in these terms.
