text_B: Hartwig Crater is a crater in the Argyre quadrangle of Mars , located at 39 ° south latitude and 16 ° west longitude .. Argyre quadrangle. Argyre quadrangle. It is 105 km in diameter and was named after Ernst Hartwig , a German astronomer -LRB- 1851 -- 1923 -RRB- .. Impact craters generally have a rim with ejecta around them , in contrast volcanic craters usually do not have a rim or ejecta deposits .. As craters get larger -LRB- greater than 10 km in diameter -RRB- they usually have a central peak .. The peak is caused by a rebound of the crater floor following the impact .. If one measures the diameter of a crater , the original depth can be estimated with various ratios .. Because of this relationship , researchers have found that many Martian craters contain a great deal of material ; much of it is believed to be ice deposited when the climate was different .
