Superburial

A superburial is similar to a mass grave, but is a term typically used by archaeologists to denote an area of dense burial activity without the negative connotations often associated with mass graves. A superburial may also span a much longer time period than is typical for a mass grave, such as a cemetery in constant use for centuries.
