The Enigmatic Moeraki Boulders: A Geological Marvel over Deep Time

-

The Moeraki Boulders, gracing Koekohe Beach in New Zealand, are a collection of remarkably large and almost perfectly spherical stones, known geologically as septarian concretions. These natural wonders, some reaching up to two meters in height and weighing several tonnes, present a captivating sight as they lie scattered across the sand, emerging from the eroding mudstone cliffs. Their formation began approximately 60 million years ago during the Paleocene epoch. At this time, the area was submerged beneath the sea. The boulders started as fossil shell, bone fragment, or other organic matter – on the ancient seafloor. Over millions of years, calcite (calcium carbonate) and other minerals gradually precipitated and accumulated around these central points within marine sediments. This slow process of concretion, layer by layer, cemented the surrounding mud and sand, eventually forming their distinctive spherical shape due to relatively uniform mineral diffusion in the soft sediment. The boulders developed internal cracks, known as septaria, which later filled with more calcite, often creating striking patterns of veins. As coastal erosion has worn away the softer surrounding mudstone, these resilient, ancient spheres have been exhumed and exposed, captivating visitors and scientists alike with their unique geological history and striking appearance.

Moeraki Boulders and a Global Flood:

A single, catastrophic global flood event cannot account for the specific and lengthy formation process of the Moeraki Boulders. These concretions require a slow, gradual accumulation of minerals around a nucleus within sedimentary layers over vast timescales – millions of years. The distinct internal structures, such as the septarian cracks filled with later generations of calcite, also point to a prolonged and multi-stage diagenetic history. A rapid, turbulent flood event would deposit mixed sediments quickly and chaotically, lacking the stable, long-term conditions necessary for the precipitation and cementation that forms such large, spherical, and internally complex structures.

How Old-Earth Creationism Accommodates This: Old-Earth Creationism (OEC) readily accommodates the scientifically determined age and formation process of the Moeraki Boulders. OEC accepts the mainstream scientific understanding of an ancient Earth, viewing geological and cosmological evidence as compatible with a divine creator. Therefore, the 60-million-year timeframe required for the boulders' concretion through natural sedimentary and chemical processes poses no conflict. OEC posits that God created the universe and Earth billions of years ago, allowing for the extended geological processes, like those that formed the Moeraki Boulders, to unfold according to the natural laws established by the Creator.

How OEC Believes in Long Genesis Days Accommodating This: Old-Earth Creationism interprets the "days" of Genesis 1 not as literal 24-hour periods but as extended epochs or ages. This "day-age" view allows for the immense timescales described by science, such as the millions of years required for the Moeraki Boulders to form through slow geological processes, to fit within the Genesis creation account.

  • Old-Earth Creationism interprets Genesis 1:20, concerning the creation of sea creatures and birds, within a framework that accommodates vast geological timescales. Rather than a literal 24-hour day, "day" in Genesis is viewed as a longer, undefined period. Old-Earth Creationists hold to a "progressive creation" view, where God created life in stages over millions of years. Thus, Genesis 1:20 signifies a period when God introduced marine and avian life, aligning with the fossil record's appearance of these creatures over extensive epochs. They emphasize that "kinds" (Hebrew: min) in Genesis refer to broader categories than modern biological species. This allows for diversification within those "kinds" over long periods.

  • Old Earth Creationism (OEC) interprets Job 9:5-6 as a description of God's immense power and sovereignty over natural forces, rather than a literal 24 hour depiction of specific, recent geological events. OEC acknowledges that mountains and geological features are formed through long, natural processes, but attributes the ultimate cause to God's design and ongoing control. "Removing mountains" and "shaking the earth" are seen as descriptions  of God's ability to orchestrate and influence the Earth's systems, including tectonic shifts and geological upheavals, over vast periods. This verse highlights God's role as the sustainer and director of the physical world, aligning with OEC's view of God working through established natural laws and deep time.

How Old-Earth Creationism Relates to God's Glory: For Old-Earth Creationists, the vastness of geological time and the intricate, slow processes that formed wonders like the Moeraki Boulders magnify God's glory, power, and wisdom. The immense age of the Earth and the complexity of its formation are seen not as a challenge to faith, but as a deeper revelation of the Creator's majestic and patient workmanship throughout cosmic history.

Celestial Visitor Returns After a Million Years: Comet C/2025 F2 (SWAN)

-
Image
Comet C/2025 F2 (SWAN), a newly discovered celestial object, boasts an astonishingly long orbital period estimated at roughly 1.4 million years. This immense timescale signifies that its current appearance in our skies is an exceptionally rare event, unlikely to be witnessed again by anyone alive today. The comet's presence offers a unique opportunity for astronomical observation and study of a long-period comet making its perihelion passage. Independently co-discovered in late March 2025 by amateur astronomers Vladimir Bezugly and Michael Mattiazzo through images captured by the SWAN instrument aboard the SOHO spacecraft, this icy wanderer provides valuable insights into the composition and dynamics of the outer solar system and the history of our planetary neighborhood. Its extended journey highlights the vastness of cosmic time and the infrequent nature of such close encounters with these primordial solar system remnants. How NASA Measures This: NASA utilizes sophist...

The Enigmatic Beauty of Morgan Hill Poppy Jasper: A Geological Wonder

-
Image
Morgan Hill Poppy Jasper, a captivating variety of orbicular jasper, is renowned for its striking patterns resembling vibrant poppy flowers. This unique gemstone originates from the foothills of the Santa Cruz Mountains, near Morgan Hill, California. Its distinctive appearance stems from the intricate interplay of silica-rich chert and iron oxides. The formation process involves the slow crystallization of silica dioxide, which forms the base matrix. Subsequent introduction of iron oxide and other mineral impurities creates the characteristic spherical orbs and colorful patterns. The hues range from deep reds and oranges to warm yellows and creamy whites, resulting in a visually stunning display. These orbs, or "poppies," are formed by the radial growth of chalcedony crystals around a central nucleus, creating the spherical patterns. Geological processes, including volcanic and seismic activity, have played a crucial role in shaping the jasper's unique feature...

Comet C/2021 A1 (Leonard) and its 80,000 year Orbit: an Old Earth Perspective

-
Image
Comet C/2021 A1 (Leonard) was a remarkable long-period comet, a wanderer from the far reaches of our solar system that captivated astronomers and skygazers alike. Before its closest approach to the Sun (perihelion) in January 2022, its inbound orbital period was estimated to be a staggering 80,000 years. This immense timeframe signifies the comet's journey from the Oort Cloud, a theoretical spherical shell of icy objects surrounding our solar system, and its long absence from the inner solar system. The comet's trajectory brought it relatively close to Earth in December 2021, offering a spectacular, albeit fleeting, display. Its perihelion passage, however, dramatically altered its path, with observations suggesting it has since been ejected from the solar system, embarking on an even longer, perhaps infinite, journey into interstellar space. The comet's age, therefore, is not easily defined by a simple start and end point, but rather by the vast stretches of ti...
