The crossing of the Galactic disk by a Globular Cluster could produce starformation due to gravitational focussing or compression of disk material. Wereport on simulations of the effect on disk material which reveal that thecrossing can sometimes cause local gravitational focussing of disk material. Wealso present the salient points of a little-known paper by Levy (2000), thatshows that strong compression can result from the shock wave generated by GCdisk crossing. The main thrust of our paper is a search for remnants of diskcrossings by Globular Clusters. Using the gravitational potential of the Galaxyto locate the position of the most recent crossings of a subset of fifty-fourGlobular Clusters reveals that systematic errors and uncertainties in initialconditions limit the scope for unequivocal identification. From the subset offifty-four, six possible search sites with the best constraints are retainedfor further scrutiny. Three of the six potentially promising search areas inthe disk are from Globular Clusters NGC 3201, 6397 and NGC 6838, for which wecannot rule out some observed star associations observed nearby as beingremnants. The three other of the six areas are too large to provide meaningfulidentification of remnants. Also, a possible remnant (open cluster NGC6231) isshown not to be due to Globular Cluster impact, contrary to a previous report.In a more wide-ranging screening of one hundred and fifty-five GlobularClusters we identify which Globular Clusters are compatible with beingresponsible for the formation of any of the Galaxy's five most prominent StarSuper Clusters.
