Carpe Diem #1533 Xenolith

Dear Haijin, visitors and travelers,

Welcome at a new episode of CDHK. This month we celebrate our 6th anniversary with prompts following the alphabet. During our existence I have created several other weblogs for our CDHK family. One of those weblogs is titled Haiku Shuukan and was a weekly haiku meme. This weblog is still open, but I am not publishing there at the moment. As I started Haiku Shuukan I started with the alphabet also and so for today I have chosen a prompt I used there; Xenolith.

Let me tell you all a little bit more about Xenolith: This prompt will not be an easy one. I had to search on the Internet to find something about this prompt. And I found the following about Xenolith at Wikipedia.

A xenolith (Ancient Greek:  “foreign rock”) is a rock fragment which becomes enveloped in a larger rock during the latter's development and hardening. In geology, the term xenolith is almost exclusively used to describe inclusions in igneous rock during magma emplacement and eruption. Xenoliths may be engulfed along the margins of a magma chamber, torn loose from the walls of an erupting lava conduit or explosive diatreme or picked up along the base of a flowing lava on Earth's surface. A xenocryst is an individual foreign crystal included within an igneous body. Examples of xenocrysts are quartz crystals in a silica-deficient lava and diamonds within kimberlite diatremes.
Although the term xenolith is most commonly associated with igneous inclusions, a broad definition could include rock fragments which have become encased in sedimentary rock. Xenoliths are sometimes found in recovered meteorites.

Here is an example of a Tanka by Georgia also known as Bastet:

war and poverty push
social cataclysms drive
human lava flows
into established homelands
creating new xenoliths

I remember that I couldn't come up with a haiku or tanka inspired on this prompt so I am looking forward to your responses.

This episode is NOW OPEN for your submissions and will remain open until November 6th at noon (CET). I hope to publish our new episode (a double one) later on. For now ... have fun!
