在霍切费尔，人们只知道三个马尔人。埃克菲尔德玛尔湖位于火山田南缘，始新世湖相沉积充填，第三纪准平原仅受到轻微侵蚀。第三纪霍舍费尔火山场(THVF)东南部的Jungferweiher Maar和东北部的Dottingen Maar的年龄尚不清楚，它们在THVF内的时间也不确定。与周围地区相比，THVF的中心部分被严重侵蚀。在这里，除了一个例外，在凯尔伯格地区发现了六个大直径(>；600米)。到目前为止，还没有在大海底发现陨石坑沉积物的遗迹。它们可能代表着被深度侵蚀的岩浆；然而，也有可能是其中两个大火山口构成了小火山口。
In the Hocheifel only three maars are known. The Eckfeld Maar, filled with Eocene lacustrine sediments, is located at the southern boundary of the volcanic field, where the Tertiary peneplain has been eroded only slightly. The ages of the Jungferweiher Maar in the southeast and the Dottingen Maar in the northeast of the Tertiary Hocheifel Volcanic Field (THVF) are unknown and their timing within the THVF is uncertain. In contrast to the surrounding area, the central part of the THVF is deeply eroded. Here, six large diatremes (>600 m) were identified in the area of Kelberg with one exception. So far, no relics of crater sediments have been found within the large diatremes. They probably represent deeply eroded maars; it is, however, also possible that two of the large diatremes constitute small calderas.
