This specimen seems to be of metamorphic paragenesis, perhaps a skarn. The matrix consist of moslt clinoziosite. The Scheelite can be readily seen as white zones in delineations and are strongly fluorescent.
This deposit was apparently the first tungten deposit to be mined in the US. An excellent summary can be read on Mindat here. I will quote an interesting portion of this reference:
"This locality (a town park), like the neighboring Old Mine Plaza (now Home Depot), is unique in Connecticut for its varied mineralogy and the area was prospected since the early 19th century. The park encompasses a number of unrelated deposits with separate prospecting and mining history and mineralogy. The town of Trumbull took the property in lieu of back taxes on October 4, 1937 and named it Old Mine Park on January 4, 1940 (Sullivan, 1985). When opened, the town parks commissioner wrote that the “portion of it which was formerly worked and exposed during mining operations will be left open to residents and non-residents who are interested in Geology or Mineralogy for the study and removal of specimens” (Whitney, 1938). Collecting is no longer allowed, however."
