1. The Bouguer gravity profiles taken from the Bouguer map in Figure 6 revealing roughly similar shape with regard to the central negative anomaly and the surrounding ring of relatively positive anomalies that are only faintly developed on the NNW–SSE profile.
The Bouguer gravity profiles taken from the Bouguer map in Figure 6 revealing roughly similar shape with regard to the central negative anomaly and the surrounding ring of relatively positive anomalies that are only faintly developed on the NNW–SSE profile. Also noteworthy is the ring of gravity lows (arrowed) beyond the suggested peak ring strongly supporting the peak or inner ring character of an originally much larger impact structure.
